macOS Server 5.2 updates Server 5.1.7. It requires OS X 10.11.6 or macOS Sierra 10.12.
On a Mac running OS X 10.11.6 or macOS v10.12, update to macOS Server 5.2 from the Updates pane of the Mac App Store. To prevent the interruption of services, Server updates aren't automatically installed, even if you've chosen to install other updates automatically from the Mac App Store.
During installation you might see the message "Server app replacement detected." This is a normal part of the update process. All Server settings and data are preserved during the update.
After installation is complete, open Server app to finish setting up your previously configured services.
