OK, so I am doing some tech support work for an office with all Macs, and they want to update to Lion. They are all running Snow Leopard, and are all capable of running Lion. The server is running Snow Leopard Server. I see that if you buy Lion once, I can use it on all the machines in the office correct? Does this work for the server as well? As in, if I update the server to Lion first, can I use that same installation for all the workstations? Or do I need at least 2 installs, one for the server, and one for all the workstations?
