active directory migration 2022 from 2008 requirements
Hello,
since the functional level are the same as 2016 I'm seraching if to promote a DC2022 in a 2008 domain and forest functional level is possible covering the same requirements as 2016.
I've read this article and the functional level works:
https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/active-directory-functional-levels
but I need confirmation about any requirements.
regards

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

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.
Just checking if there's any progress or updates? Please don't forget to mark helpful replies.
