How can I update windows server 2012 r2 foundation with other versions?
You can perform a migration.
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, transfer pdc emulator role, use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.

- Thank' s for your suggestion, I will try to do this step even if it is very long.
MauroSounds good, you're welcome, usually takes about an hour to do.
