My company needs to upgrade OS on all PI Servers, since they are running on Win 2008 R2. I have read the manuals on moving a PI Server, but I am wondering if anyone with experience in this could list any important points or pitfalls? I am hoping to avoid as much dataloss/downtime as possible.
We have a lot of servers, PI Archive, PI AF and different interface servers. They are all running on virtual VM-ware machines, so this is what I am thinking.
-Make sure as much as possible of interfaces run buffering
-Create new virtual servers with new operating system (2012 or preferably 2019) with the same IP address/server name etc. identical to existing servers.
-Install all PI applications on new servers.
-Shut down existing servers
-Boot up new servers
Hopefully this should make downtime minimal. Any advice on this would be appreciated.
