I am in the middle of rebuilding my 6 server farm. The data collector in the farm was running PS 4.0 and I am upgrading to 4.5. I have two other servers running 4.5 that are already built and in production. I changed the data collector from the previous to the new and now I get errors stating that the data store is not available. When I run the query farm command it shows that the data collector is now the server that I set it to but now I can’t run discovery on the other servers. What do I have to do to ensure that I have a connection to the data store and to ensure that my farm is stable?
