Finally took the plunge and upgraded to Mavericks, wasn’t sure how it’d go with the Server but I have to hand it to Apple, smoothest upgrade thus far.
After you upgrade the client to Mavericks you get a notice from the Server.app saying it needs updating. Download it from the App Store, launch it and it’ll automagically upgrade everything and after that everything was working as before. Nice.
So yeah, the only downside to the whole process is the name. Mavericks. Really?
