SolidWorks 2018 SP2

I just noticed that the full release of SP2 is out. Coming from 2018 SP1, is there any special order that the server/client should be upgraded? Does the server need to be updated first? Will clients lose access if they haven't upgraded to SP2.0 before the server, or will clients lose access if they do upgrade to 2.0 and the server is still at 1.0? Thanks.
