    Hello,

    The standard license is sufficient for a ___domain controller. it's recommended to use Standard , because it's less expensive, and there is no difference between the both version.

    No, you cannot downgrade the installation of windows from DataCenter to Standard. The simplest solution is to stand up a new one for replacement.

    The two prerequisites to introducing the first 2019 ___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, 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.
