That depends on which method you employ to upgrade your server and what exactly you understand under "upgrade or migration".

If you mean a OS level upgrade: it can be done several ways. One way would be a "alt-disk-install", durich which the system will be available, save for a reboot.

If you mean hardware upgrade and/or DLPAR migration: yes, this is also possible while the system is under load. Hardware chamges itself can cause downtimes, depending on what you want to change and how much hardware you have: Memory and CPUs need a downtime of the machine, but with enough hardware resources you could live-migrate the LPARs to (an)other machine(s), do the upgrade and migrate them back.

All these methods depend on a certain infrastructure which you may or may not have available. So tell us, what you want to do, what you have and we give you a honest anwer instead of throwing around wild guesses.
