I need to migrate a full-fledge intranet portal running on SP13, with lots of custom made applications, into another domain. With some 5TB data.
I have gone the various blogs to get the approach but didnt find a solid one.
we planned to create a new farm in the new domain and restore the content DB of old farm into new, and then move custom solutions one by one.
pls tell if is the right approach of doing it !
One more requirement is that the user will be able to login via their both IDs (from old domain as well as new domain) and land to same User profile (profile content and apps are customized on the bases of rights) on both logins.
How can we achieve this ? Do we need to migrate the User too or it will migrate by default!
