Making a new version with file outside vault

Out vault was offline for a few days (server upgrade). During that time a number of people saved files outside of the vault so they could continue working. Now I would like to put those files into the vault, presumably as new versions of existing parts. Any ideas on how to do this? I was thinking of checking out the file, overwriting it on my computer with the off-line version and then checking it in as a new version. Wanted to get input from the community before trying.
