Domain Controller Migration and Upgrade other consideration

Question

When I migrate the Domain Controller to another server including AD services, Is there any services such as DNS, DFS File Shares and other Windows Services, etc etc to be taken in to consideration on this migration. I don't want to miss anything because Users use File Shares, Printers, GPs, etc

Thanks

Not sure what you're asking about? Standing up a new domain controller?

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.
