Hi Dudes,

Just wondering how I can migrate two old 2012 servers to Server 2019 Data Centre:
So I would like to migrate Radius Server Currently used by our Cisco WLAN controller and Certificate Authority Servers from Server 2012 to New Server 2019, what would be the best procedure without much outages?

Thanks a lot,

    Hi Mang,

    You are welcome. Thank you so much for your kindly reply.

    Yes, it is suggested that we need to uninstall CA server from the source server. It is important to remove the CA role service from the source server after completing backup procedures and before installing the CA role service on the destination server.

    "Although it is not recommended, some administrators may choose to leave the CA role service installed on the source server to enable the source CA to be brought online quickly in the case of migration failure. If you choose not to remove the CA role service from the source server before installing the CA role service on the destination server, it is important that you disable the Active Directory Certificate Services service (Certsvc) and shut down the source server before installing the CA role service on the destination server. Do not remove the CA role service from the source server after completing the migration to the destination server. Removing the CA role service from the source server after migrating to the destination server interferes with the operation of the destination CA."

    For more information, we could refer to:

    Hope the information is helpful. Thank you so much and have a nice day.
