hi Laura. Thanks for the heads up. I have a plan to upgrade but it is complicated. Our govt funds MS software and some Novell/MF software for schools that includes GW. Somehow somewhere the latest contract negotiations are stalled so while I have access to the software I can't get a licence key. I had read somewhere I need a key. If I don't need a key then that I could upgrade. If I go down the 2018 path I'll probably move to a new server and do a migration.
GroupWise 18 does require you to have a current/active maintenance contract. To license GroupWise 18 you don't use a license key specifically but rather authenticate to the Customer Care Center (NCC) to validate your maintenance agreement.
