How do I check in documents that were checked out during a 2010 -> SPO migration?

[lumberjacklurch]

I have a document library that was migrated from a SP 2010 site.  Apparently, some of the documents in this library were checked out at the time of the migration.  I know the best practice is to check in all files before migration, but it's too late for that (I didn't perform the migration).  Is there some method (ex PowerShell) that I can force check in the files?

@lumberjacklurch  This one might be worth trying: https://gallery.technet.microsoft.com/office/Find-all-checked-out-files-56fd562d

Thanks for the reply.  That post is from 2016.  Is there a more updated version?
