We need to migrate a site from SharePoint 2010 in Domain A to SharePoint 2013 in Domain B. Domain B has a trust to Domain A and it is planned to keep the users in Domain A - they won't get migrated to the new environment.
Normally when we do migrations where there is a domain change we have to migrate the users (Move-SPUser) but in this case (where we don't move the AD accounts) I don't know if this is necessary. Well surely we have to setup new service and app pool accounts for the site to run on the new server but do any of you know if there may be a chance that even as we don't migrate the users if we have to change them somehow?
The users will be used to log on to the SharePoint in Domain B and there is data in the site that uses these users and those links should be kept intact.
Btw: SP2010 uses classic authentication and in SP2013 we will be using claims authentication.
