- I don't think that scaling up will be a problem, take note however of this paragraph in :
https://www.cisco.com/c/en/us/td/docs/net_mgmt/prime/infrastructure/3-9/release/notes/bk_Cisco_Prime_Infrastructure_3_9_0_Release_Notes.html
>..
If your existing Prime Infrastructure is 3.7.x or 3.8.x, and your upgrade path contains 3.4.x or earlier versions, then you cannot in-line upgrade that server to Prime Infrastructure 3.9 due to security vulnerabilities in the underlying Red Hat 6 installation. You will need to take a backup of the Prime Infrastructure 3.7.x or 3.8.x server, deploy a fresh Prime Infrastructure 3.9 server, and restore that backup into the Prime Infrastructure 3.9 server.
The benefits in this case that using or playing with vm's gives easy testing options w.r.t your question without too much impact and or fallback to current prime installation(s).
