Hi, we're currently testing a migration back to self-hosted and are running into a strange issue where we're getting warnings that the following files have been modified. We've re-downloaded them and confirmed what's on the server matches the downloads, but the warning persists. Any ideas?

applications/cms/api/records.php
applications/cms/extensions/core/FileStorage/Records.php
system/Content/Item.php
system/MFA/GoogleAuthenticator/Handler.php

I think this is related to a patch which hadn't been applied on our cloud install. So, can be ignored. 

Yes, you should upload a fresh set of files then run the upgrader from /admin/upgrade
