Migrating an on-prem Sharepoint to O365 Sharepoint/teamsite using SPMT. There are no special permissions on this site, everyone can see everything, so I was thinking of not using a mapping file.
Assuming there's no mapping file used, what happens to the historical versioning of the files?
Will the new Sharepoint site still show the names of the people who edited the versions? Or do the versions still remain, but without names?
