We have about 10 fairly large (100 GB - 200 GB) site collections on SharePoint 2016 and we need to move these into another farm in another company. I know with database detach/attach and site collection backup/restore options the version/CU of SharePoint matters. If we can get those to match properly, is there a way to map users to a new domain?

I know that migration tools can do this with basically a CSOM approach, but it seems that a content database detach/attach may be the quickest option if I can overcome the user mapping complication.

You can use Move-SPUser or stsadm -o migrateuser to migrate from one account to another (if using Windows claims, make sure you pass the -IgnoreSID switch for Move-SPUser).

There are other tools, such as Sharegate, which allow you to remap user accounts from one object to another.

  • Thanks, Trevor. So an approach might be to detach/attach the content database from one domain/company to the other, then run Move-SPUser after in the new environment? Commented May 14, 2020 at 13:55

    That's correct.
