Hello Tech Community
Please advise on the proper path i have exchange 2008R2 server which i am running my DC-ADDS and exchange 2010 server in one server. I am migrating my DC to another server Win 2019 standard where a will migrate all FSMO roles to make it the primary DC thereafter dcpromo or remove ad role from the 2008 box (please bear this server is hosting exch 2010 - will this not affect services on exch?). Thereafter i will raise forest functional level to 2012.
Please advise on recommended procedure for server 2008-2019 without affecting the exchange services.

here are some steps to guide you through the process:
As for your Exchange 2010 server, it’s generally recommended to separate your Domain Controller and Exchange server roles. Running both on the same server is not a recommended practice and can lead to complications. You might want to consider migrating your Exchange server to a separate server as part of this process.

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.
