    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.

    How to migrate using one of three streamlined methodologies:

    Quick Migration (where you don’t know if your domain controllers are healthy, and you want a rollback option)

    Express Migration (where you are sure that your domain controllers are healthy, and you want a rollback option)

    Hyper Migration (where you want to migrate with the minimum steps and are confident of domain controller health)

    Какой метод вы можете использовать, вы можете сделать reference в зависимости от вашей ситуации:
