Hi Thomas
I hope you're doing well today!
Thank you for using Microsoft Advertising Forum Community. I'll be happy to provide you information regarding your concern on creating/updating the name for your campaign and ad groups during import from Google.
Please be informed that there are two options in doing Google import. It can be the regular import option which can be found on the campaigns section or the import from Merchant center.


Now that you've imported your campaigns from Google Ads, you can check the status of your import, review error logs, and edit, pause, or delete your import schedule. Keep in mind that not all information will be imported, but that doesn't mean it's not supported within Microsoft Advertising. So, after you import, be sure to review your campaigns to make sure everything is good to go and add the missing information back to your campaigns.
Kindly check the Main entities imported and updated for search campaigns. Please see resource: What gets imported from Google Ads (microsoft.com)
Campaign name: Campaign names in Microsoft Advertising are not case-sensitive. If you import or re-import campaigns named “Coffee Sales” and “coffee sales” from Google Ads, you will see an error for a duplicate campaign name. However, if you import a campaign named “Coffee Sales” under an account that already contains a campaign named “coffee sales”, we recognize them as the same, and will update accordingly.
Ad group name: Ad group names in Microsoft Advertising are not case-sensitive. If you import or re-import ad groups named “Coffee Sales” and “coffee sales” from Google Ads, you will see an error for a duplicate ad group name. However, if you import a campaign named “Coffee Sales” under a campaign that already contains an ad group named “coffee sales”, we recognize them as the same, and will update accordingly.
Suggested workaround:
You can edit a campaign or ad group name once it was successfully imported from Google ads to Microsoft advertising.

I hope the information provided here will partly answer your question. If you have any additional questions, please reply to this post or reach out to our support.
Thank you,
