We have recently obtained a unlimited server license and it is my
understanding that you have to uninstall all of the current user
licenses. I assume that this will go well, but as a "just in case" I
would like to be able reinstall the old licenses if needed. I was
testing this and it appears there are a few users licenses that were
upgrades and require an activation key. This was done years ago by
another person not longer with the company. I went to the activation
link and it asks for the old license s/n which I also don't know. The
licenses in question are still installed, is there some way of telling
from the installed license what the activation key was?
