Switch a computer hosting the FactoryTalk Directory server

This capability allows you to provision a new FactoryTalk Directory server in parallel with an existing server. If you specify the FactoryTalk Directory sever on each client computer using a DNS alias name, you don’t have to reconfigure each FactoryTalk Directory client computer after switching over from the existing FactoryTalk Directory server to the new one.
Prerequisites
  • Ensure that the existing FactoryTalk Directory server is associated with a DNS alias name.
To switch a computer hosting the FactoryTalk Directory server
  1. In the DNS server, configure the DNS alias name with the fully qualified domain name of the target server computer.
  2. Back up the existing FactoryTalk Directory server’s configuration before switching to the target server computer.
    Restoring the configurations in the target server computer ensures that the applications created in the previous computer run properly, and then restart the target server computer.
    The backup sever must be online.
  3. On the target server computer, open FactoryTalk Administration Console, and then check the
    DNS alias name of the FactoryTalk Directory server
     security policy to make sure that the configuration is correct.
  4. After getting the notification of server changes on each client computer, restart each client computer.
    TIP:
    If you restart the client computers before getting the notification, some dependent services, like FactoryTalk Linx service, might not be able to switch to the new FactoryTalk Services Platform server and you must restart the client computers again.
    We recommend that you restart the client computers hosting HMI servers, FactoryTalk Alarms and Events servers, and FactoryTalk Linx servers before restarting the other client computers to make sure that all client computers are able to run properly.
