AD migration methods / tools

Question

I am looking for AD migration methods / tools for two scenarios:

1. I would like to upgrade v. old Windows Server 2008R2 with Exchange Server 2010 to new build.
2. I would like to split some AD users & file sharing to the other new build Windows Server.

Any free tool(s) for AD users migration from AD-1 to new AD-2? need pay for Binary Tree for safe?

Is it good for use 'robocopy' for files migration?

Answer 1

1 - The two prerequisites to introducing the first 2019 or 2022 domain controller are that domain functional level needs to be 2008 or higher and older sysvol FRS replication needs to have been migrated to DFSR

I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting any operations. Then stand up the new 2019 or 2022, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.

You could start a new thread here about your exchange migration here.
