Frequently asked questions

1. When do you remove the old setup after server migration?

Do not remove the old setup until all the agents start reporting to the new setup.The agents and the distribution servers, during their next contact, will pick up the details of the new server and start communicating with the new server subsequently. You will need to run the Endpoint Central Servers at both the installations till all the agents start reporting to the new server. Once all the agents have contacted the new server, you can then uninstall the old server.
