Best thing to do is keep a change log. That way if you make any changes to core files, you can reapply the file change if necessary.
When vivvo releases patches, then only include the files that have changes made to them... so you'd simply need to take a quick look at your change log and the patch/maintenance to see if any files have been effected. If so, edit those files prior to uploading.
I have sites that are heavily modified (lots of core file edits). With my change log, it makes upgrading a breeze.. without it would be a nightmare lol
