Moving server.app to a new machine
There are a number of threads started by people wanting to download older versions of Server.app which seems as if it isn't possible. I'm wondering whether it's possible to move an existing installation in some way.
I have an old Mac mini running El Capitan and Server 5.2 but am having problems with it and am migrating it to a VM on a different Mac. Despite the OS being the same, if I log in using the same Apple ID and try to download Server.app I have to pay for it. It does not appear in the "Purchased" tab. On the original Mac it also does not appear in the "Purchased" tab but searching for it give the option to upgrade. Since (I assume) the upgrade won't download a full installer which I can transfer to the new machine, I'm wondering if it is possible to move the installed app.
The price to buy it again is not high but as I'm in the process of moving away from server and I've already had to pay twice because the last OS upgrade removed the previous version of Server, I'd prefer not to have to buy it again (even though I no longer use services which have been removed from the latest version).
I don't need to move the configuration, and want to avoid using existing backups if I can to keep the VM as "clean" as possible.
Mac mini, OS X 10.11
