Hi, I have a couple of questions around licencing. I'm new to SQL Server and
am having a hard time tracking down product keys and licence types in the
servers.

1/ How can I check if an instance has been installed using an MSDN licence?
I can see version, type(enterprise vs standard) etc but cannot find a
reference to MSDN. I've taken over from someone and need to be sure what I
can do with each instance from a licence point of view.

2/ Is it possible to change the licence used from Full Enterprise to MSDN
Enterprise. I've got a full enterprise server which no longer has a use,
rather than just delete it I was going to convert it to use MSDN licencing so
I had a ready built test db. I found the "Edition Upgrade" wizard in
installation but I'm not sure where to find the product key since it's built
into the install exe.

Thanks
