Symptoms
While running a migration, the app returns the following error:
The Central Administration for site [sitename] could not be found.
Error code
IN-951-399
IN-952-399
Details
You usually get this error when you have a custom URL (often called vanity URL) that differs from the standard format, [name]-admin.sharepoint.com, for your SharePoint Admin center. ShareGate Migrate cannot locate the admin page.
Solution
Though ShareGate Migrate does not support vanity URLs, our support team can help you configure the app to point to your SharePoint admin center with your vanity URL in some cases.
Contact our support team to see if it's possible; they'll gladly assist you.
Note: The support specialist will require diagnostic data, and they will send instructions to help you set this up. We cannot guarantee that this will work.
