New-MigrationBatch

This parameter is available only in the cloud-based service.

{{ Fill AdoptPreexisting Description }}

This parameter is available only in on-premises Exchange.

The AllowIncrementalSyncs parameter specifies whether to enable or disable incremental synchronization. Valid values are:

• $true: Incremental synchronization is enabled. Any new messages that are sent to the source mailbox are copied to the corresponding target mailbox once every 24 hours. This is the default value.
• $false: Incremental synchronization is disabled. The migration batch will go into the Stopped state after the initial synchronization is complete. To complete a migration batch for local moves, cross-forest moves, or remote move migrations, you need to enable incremental synchronization by using the Set-MigrationBatch cmdlet.

The AllowUnknownColumnsInCsv parameter specifies whether to allow extra columns in the CSV file that aren't used by migration. Valid values are:

• $true: The migration ignores (silently skips) unknown columns in the CSV file (including optional columns with misspelled column headers). All unknown columns are treated like extra columns that aren't used by migration.
• $false: The migration fails if there are any unknown columns in the CSV file.This setting protects against spelling errors in column headers. This is the default value.

This parameter is available only in the cloud-based service.

{{ Fill Analyze Description }}

This parameter is available only in the cloud-based service.

{{ Fill ArchiveDomain Description }}

The ArchiveOnly switch specifies that only archive mailboxes are migrated for the users in the migration batch (primary mailboxes aren't migrated). You don't need to specify a value with this switch.

You can only use this switch for local moves and remote move migrations.

You can use the TargetArchiveDatabases parameter to specify the database to migrate the archive mailboxes to. You can also specify the target archive database in the CSV file. If you don't specify the target archive database, the cmdlet uses the automatic mailbox distribution logic to select the database.

The AutoComplete switch forces the finalization of the individual mailboxes as soon as the mailbox has completed initial synchronization. You don't need to specify a value with this switch.

You can only use this switch for local moves and remote move migrations.

If you don't use this switch, you need to run the Complete-MigrationBatch cmdlet to finalize a migration batch.

This parameter is available only in the cloud-based service.

{{ Fill AutoProvisioning Description }}

This parameter is available only in on-premises Exchange.

The AutoRetryCount parameter specifies the number of attempts to restart the migration batch to migrate mailboxes that encountered errors.

The AutoStart switch immediately starts the processing of the new migration batch. You don't need to specify a value with this switch.

If you don't use this switch, you need to manually start the migration batch by using the Start-MigrationBatch cmdlet.

This parameter is available only in the cloud-based service.

{{ Fill AvoidMergeOverlap Description }}

The BadItemLimit parameter specifies the maximum number of bad items that are allowed before the migration request fails. A bad item is a corrupt item in the source mailbox that can't be copied to the target mailbox. Also included in the bad item limit are missing items. Missing items are items in the source mailbox that can't be found in the target mailbox when the migration request is ready to complete.

Valid input for this parameter is an integer or the value unlimited. The default value is 0, which means the migration request will fail if any bad items are detected. If you are OK with leaving a few bad items behind, you can set this parameter to a reasonable value (we recommend 10 or lower) so the migration request can proceed. If too many bad items are detected, consider using the New-MailboxRepairRequest cmdlet to attempt to fix corrupted items in the source mailbox, and try the migration request again.

Note: This parameter is being deprecated in the cloud-based service. In the future, if neither the BadItemLimit or LargeItemLimit parameters are specified, the migration will use Skipped Item approval semantics instead of BadItemLimit semantics.

This parameter is functional only in the cloud-based service.

The CompleteAfter parameter specifies a delay before the batch is completed. Data migration for the batch will start, but completion won't start until the date/time you specify with this parameter.

Use the short date format that's defined in the Regional Options settings on the computer where you're running the command. For example, if the computer is configured to use the short date format MM/dd/yyyy, enter 09/01/2018 to specify September 1, 2018. You can enter the date only, or you can enter the date and time of day. If you enter the date and time of day, enclose the value in quotation marks ("), for example, "09/01/2018 5:00 PM".

In Exchange Online PowerShell, if you specify a date/time value without a time zone, the value is in Coordinated Universal Time (UTC). To specify a value, use either of the following options:

• Specify the date/time value in UTC: For example, "7/30/2020 9:00PM Z".
• Specify the date/time value in your local time zone: For example, "7/30/2020 9:00PM -700". The value will be converted to UTC if you don't use the TimeZone parameter.

The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

• Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.
• Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.

This parameter is available only in the cloud-based service for IMAP migration and Google Workspace migration.

The ContentFilter parameter uses OPATH filter syntax to filter the messages by Received time. Only content that match the ContentFilter parameter will be moved to Exchange online. For example:

• "Received -gt '8/23/2020'"
• "Received -le '2019/01/01'"
• "Received -gt '8/23/2015' -and Received -lt '8/23/2020'"

You can specify the language by using the ContentFilterLanguage parameter.

This parameter is available only in the cloud-based service for IMAP migration and Google Workspace migration.

The ContentFilterLanguage parameter specifies the language being used in the ContentFilter parameter for string searches.

Valid input for this parameter is a supported culture code value from the Microsoft .NET Framework CultureInfo class. For example, da-DK for Danish or ja-JP for Japanese. For more information, see CultureInfo Class.

The CSVData parameter specifies the CSV file that contains information about the user mailboxes to be moved or migrated. The required attributes in the header row of the CSV file vary depending on the type of migration. For more information, see CSV files for mailbox migration.

A valid value for this parameter requires you to read the file to a byte-encoded object using the following syntax: ([System.IO.File]::ReadAllBytes('<Path>\<FileName>')). You can use this command as the parameter value, or you can write the output to a variable ($data = [System.IO.File]::ReadAllBytes('<Path>\<FileName>')) and use the variable as the parameter value ($data).

Note: This parameter doesn't validate the availability of the mailboxes based on RBAC scope. All mailboxes that are specified in the CSV file will be migrated, even if they are outside of the RBAC scope (for example, an OU) that gives the admin permissions to migrate mailboxes.

The DisableOnCopy switch disables the original migration job item for a user if you're copying users from an existing batch to a new batch by using the UserIds or Users parameters. You don't need to specify a value with this switch.

This parameter is available only in on-premises Exchange.

The DisallowExistingUsers switch prevents the migration of mailboxes that are currently defined in a different migration batch. You don't need to specify a value with this switch.

A validation warning is displayed for any pre-existing mailbox in the target destination.

This parameter is available only in on-premises Exchange.

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.

This parameter is available only in the cloud-based service.

The ExcludeDumpsters switch specifies whether to migrate public folder mailboxes without including the contents of the Recoverable Items folder (formerly known as the dumpster). You don't need to specify a value with this switch.

You use this switch only in public folder migrations from Exchange 2013 or later to Exchange Online.

This parameter is available only in the cloud-based service.

For an IMAP migration or Google Workspace migration, the ExcludeFolders parameter specifies mailbox folders that you don't want to migrate from the source email system to the cloud-based mailboxes. Specify the value as a string array and separate multiple folder names with commas.

For IMAP migration, use folder names relative to the IMAP root on the source mail server. For Google Workspace migration, use label names on the source mail server.

Folder names aren't case-sensitive, and there are no character restrictions. Use the following syntax:

<FolderName>/*: Use this syntax to denote a personal folder under the folder specified in the SourceRootFolder parameter, for example, MyProjects or MyProjects/FY2010.

#<FolderName>#/*: Use this syntax to denote a well-known folder regardless of the folder's name in another language. For example, #Inbox# denotes the Inbox folder even if the Inbox is localized in Turkish, which is Gelen Kutusu. Well-known folders include the following types:

• Root
• Inbox
• SentItems
• Outbox
• DeletedItems
• Calendar
• Contacts
• Drafts
• Journal
• Tasks
• Notes
• AllItems
• JunkEmail
• Archive

If the user creates a personal folder with the same name as a well-known folder and the # symbol surrounding it, you can use a backslash (\) as an escape character to specify that folder. For example, if a user creates a folder named #Notes# and you want to specify that folder instead of the well-known Notes folder, use the following syntax: \#Notes\#.

Wildcard characters can't be used in folder names.

This parameter is available only in the cloud-based service.

{{ Fill ForwardingDisposition Description }}

{{ Fill GoogleResource Description }}

This parameter is available only in the cloud-based service.

For an IMAP migration or Google Workspace migration, the IncludeFolders parameter specifies mailbox folders that you want to migrate from the on-premises email system to the cloud-based mailboxes. Specify the value as a string array and separate multiple folder names with commas.

For IMAP migration, use folder names relative to the IMAP root on the source mail server. For Google Workspace migration, use label names on the source mail server.

Folder names aren't case-sensitive, and there are no character restrictions. Use the following syntax:

<FolderName>/*: Use this syntax to denote a personal folder under the folder specified in the SourceRootFolder parameter, for example, MyProjects or MyProjects/FY2010.

#<FolderName>#/*: Use this syntax to denote a well-known folder regardless of the folder's name in another language. For example, #Inbox# denotes the Inbox folder even if the Inbox is localized in Turkish, which is Gelen Kutusu. Well-known folders include the following types:

For example, if a user creates a folder named #Notes# and you want to specify that folder instead of the well-known Notes folder, use the following syntax: \#Notes\#.

Wildcard characters can't be used in folder names.

The LargeItemLimit parameter specifies the maximum number of large items that are allowed before the migration request fails. A large item is a message in the source mailbox that exceeds the maximum message size that's allowed in the target mailbox. If the target mailbox doesn't have a specifically configured maximum message size value, the organization-wide value is used.

For more information about maximum message size values, see the following topics:

• Exchange 2016: Message size limits in Exchange Server
• Exchange Online: Exchange Online Limits

Valid input for this parameter is an integer or the value unlimited. The default value is 0, which means the migration request will fail if any large items are detected. If you are OK with leaving a few large items behind, you can set this parameter to a reasonable value (we recommend 10 or lower) so the migration request can proceed.

Note: This parameter is being deprecated in the cloud-based service. In the future, if you don't use this parameter, Skipped Item approval semantics will be used instead.

This parameter is available only in on-premises Exchange.

The Local switch specifies a local move (mailboxes are moved to a different mailbox database in the same Active Directory forest). You don't need to specify a value with this switch.

This parameter is available only in on-premises Exchange.

The Locale parameter specifies the language for the migration batch.

Valid input for this parameter is a supported culture code value from the Microsoft .NET Framework CultureInfo class. For example, da-DK for Danish or ja-JP for Japanese. For more information, see CultureInfo Class.

This parameter is available only in the cloud-based service.

• SettingTargetAddress: Don't set the target email address on the source mailbox. This setting prevents mail from being forwarded from the original mailbox to the new migrated mailbox.

This parameter is only enforced for staged Exchange migrations.

The SourceEndpoint parameter specifies the migration endpoint to use for the source of the migration batch. You create the migration endpoint by using the New-MigrationEndpoint cmdlet. You can use any value that uniquely identifies the migration endpoint. For example:

• Name (the Identity property value)
• GUID

The StartAfter parameter specifies a delay before the data migration for the users within the batch is started. The migration will be prepared, but the actual data migration for the user won't start until the date/time you specify with this parameter.

Use the short date format that's defined in the Regional Options settings on the computer where you're running the command. For example, if the computer is configured to use the short date format MM/dd/yyyy, enter 09/01/2018 to specify September 1, 2018. You can enter the date only, or you can enter the date and time of day. If you enter the date and time of day, enclose the value in quotation marks ("), for example, "09/01/2018 5:00 PM".

In Exchange Online PowerShell, if you specify a date/time value without a time zone, the value is in Coordinated Universal Time (UTC). To specify a value, use either of the following options:

• Specify the date/time value in UTC: For example, "7/30/2020 9:00PM Z".
• Specify the date/time value in your local time zone. For example, "7/30/2020 9:00PM -700". The value will be converted to UTC if you don't use the TimeZone parameter.

The TargetArchiveDatabases parameter specifies the database where the archive mailboxes specified in the migration batch will be migrated to. You can use any value that uniquely identifies the database. For example:

• Name
• Distinguished name (DN)
• GUID

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

When you enter multiple values, the migration service selects one database as the target database to move the archive mailbox to.

You can only use this parameter for local moves and remote move migrations.

The TargetDatabases parameter specifies the identity of the database that you're moving mailboxes to. You can use any value that uniquely identifies the database. For example:

• Name
• Distinguished name (DN)
• GUID

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

When you enter multiple values, the migration service selects one database as the target database to move the mailbox to.

You can only use this parameter for local moves and remote move migrations.

If you don't use this parameter for a local move, the cmdlet uses the automatic mailbox distribution logic to select the database.

The TargetDeliveryDomain parameter specifies the FQDN of the external email address created in the source forest for the mail-enabled user when the migration batch is complete.

This parameter is required for remote move onboarding and remote offboarding migration batches

The TargetEndpoint parameter specifies the migration endpoint to use for the destination of the migration batch. You create the migration endpoint by using the New-MigrationEndpoint cmdlet. You can use any value that uniquely identifies the migration endpoint. For example:

• Name (the Identity property value)
• GUID

This parameter defines the settings that are used to connect to the destination server where the mailboxes will be moved.

The TimeZone parameter specifies the time zone of the administrator who submits the migration batch.

A valid value for this parameter is a supported time zone key name (for example, "Pacific Standard Time").

To see the available values, run the following command: $TimeZone = Get-ChildItem "HKLM:\Software\Microsoft\Windows NT\CurrentVersion\Time zones" | foreach {Get-ItemProperty $_.PSPath}; $TimeZone | sort Display | Format-Table -Auto PSChildname,Display.

If the value contains spaces, enclose the value in quotation marks (").

In on-premises Exchange, the default value is the time zone setting of the Exchange server.

In Exchange Online, the default value is UTC.

The UserIds parameter specifies the users that you want to copy from an existing migration batch (for example, if a previous migration was partially successful). You identify a user by email address or by their Guid property value from the Get-MigrationUser cmdlet. You can specify multiple users separated by commas.

The users that you specify for this parameter must be defined in an existing migration batch.

To disable the migration of the users in the original migration batch, use the DisableOnCopy switch with this parameter.

The Users parameter specifies the users that you want to copy from an existing migration batch (for example, if a previous migration was partially successful). You identify the users by using the Get-MigrationUser cmdlet. For example:

$Failed = Get-MigrationUser -Status Failed

New-MigrationBatch -Name "Retry Failed Users" -Users $Failed

The users that you specify for this parameter must be defined in an existing migration batch.

To disable the migration of the users in the original migration batch, use the DisableOnCopy switch with this parameter.
