Hi, I am upgrading an IP Office currently at rls 8.1.73 and have the plds upgrade license file. With previous sites (rls 9) I was able to just go to license/upload plds and choose the correct file. In rls 8.1.73 that is not an option. I was told I could perform the upgrade (to rls 10.1) first an then upload the upgrade license without issue. Can anyone tell me of this is correct? Or is there some other process that is best? Thanks for any help.
