Okay, I love OneDrive!!
I was able to write a small console application that took the metadata from my old OneDrive backups, wrote that into the new backups, and then delete the original old backup.
The part that shocked me the most was you can write the desired changes to the local placeholder files. The whole operation updated and deleted thousands of files in less than one minute. It was so fast I thought something went wrong. OneDrive just synced back the metadata without needing the files locally.
I know the date issue has been a problem on corporate migrations, so they must have built that in to they sync process.
If anyone else finds themselves in the same situation, I'd be happy to help.
