    You can follow along here to take a full backup.

    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.

    Hello there,

    Always backup the System State, which includes DNS Server, Windows System Files, DC Registry, Sysvol directory, COM+ Class Registration Database, Certificate Services Database, etc.

    Use the following procedure to perform a system state backup on a DC by using Windows Server Backup or wbadmin.exe.
