Any way to make a test avatar live if I've since lost the files?

I was working on an avatar a long while ago, and found that the version I made live has a bug that’s not present in the older, test version of it.
Only issue is, I don’t have those older files since my PC got wiped after a buggy windows update :confused:. Wondering if there’s a way I can make it live, as my only option in the SDK is to delete it. Any help would be lovely!
