Migrate UCS -> UCS with new domain name

Is there any tutorial on how to migrate users, groups, files, gpo’s and permissions from UCS with old domain (test.mycompany.tld) to new domain-installation (productive.mycompany.tld)?

Curious if you figured this one out? I am in need of the same thing now.

hey there

I wasn’t. I had to do a fresh-install and migrate everything manually.
