Migration Assessment Scan: External List
Overview
External lists are those lists that were created from a Business Catalogs Services [BCS] application. These are lists that appear to be SharePoint Lists, but are actually backed by an external datasource. For example, you could have a list that is showing data from an external SQL Server or Web Service.
Data Migration
BCS applications aren't migrated to the target environment. As a result, External Lists aren't migrated.
See Migration Assessment Scan: BCS for more information about BCS.
Important
Any site that is configured as "No Access" (locked), in SharePoint will be skipped. To see a list of locked site collections see the Locked Sites scan output.
Preparing for Migration
Build out a plan for the external lists. It's possible to configure Hybrid BCS to access on-premises data from SharePoint in Microsoft 365, but this will require some planning.
See Migration Assessment Scan: BCS for more information about BCS
Post Migration
Ensure that your solutions, which rely on the BCS applications, function with the newly deployed BCS applications.
