I have QS June 17 and QV 12.1 SR7.
Today I use NP 16 with QV and I want to upgrade the NP to one of the new version
and connect both QS and QV to the same NP.
All of the components ( QS, QV, NP) have a different server.
Is that possible?
Whats the condition that I have to follow up to so it'll work.
It is possible,
it is all there.
Make sure you follow requirements - read them carefully (especialy about domain settings, ports, setup, account setup, security groups and roles for service accounts). Read also about unsupported configurations as you may be surprised what is supported and what is not!
It is all in help document
