Symptoms
When using the Clean Limited Access feature in ShareGate Migrate, SharePoint may remove a user's personal views on lists where the user has Limited Access permissions.
Details
This issue is due to a limitation in SharePoint. When removing the Limited Access for a specific user, SharePoint doesn't validate that the user still has access rights through SharePoint Groups or Security Groups: it assumes that the user no longer has access to this list, and will therefore remove their personal views.
