During a migration from Google Sites to SharePoint, the migration or audit task fails with the following error message: “Invalid sites path (WebspaceNotFound)”.
The site does not exist or your migration account (defined in the source connect) doesn’t have enough permissions to access this site.
Make sure, that the site exists in your source domain. To check it, try to open the site with the credentials provided in your source connector in a navigator and this confirms that the site is not accessible. You will see an error ‘Site not found’:
You are trying to migrate the new version of Google sites, which doesn’t contain /a in their URL.
Automatically the platform adds it to your URL and hits the indicated error.
Currently new version of Google sites is not supported. You can only migrate site of older version (with /a in its URL).
