Hey guy's
I have to upgrade an ip office from 8.1 to 9.1,I have the license file for it.
Now do I just install the license and its done or they are other major steps to do it.
I am doing this for a big Avaya vendor which I can get support no problem, but I would like to try it myself cause its the best way to learn and would make me look good with them since I get alot of work from them,
any advice would be awesome
ccheers Alain
