Upgrade and migrate data on your macOS Server
Find out how to upgrade your macOS Server and migrate your server data.
You can upgrade to the latest version of macOS Server from the Mac App Store. If you move to a new server, you can use Migration Assistant to copy server data and settings from your previous server.
Before you begin
If your Mac uses macOS High Sierra or later, you can upgrade and migrate to the latest version of macOS Server. If your Mac uses an older version of macOS, find out how to upgrade your macOS Server from an earlier version.
Before you upgrade or migrate your macOS Server, follow these steps:
Back up your server with Time Machine or another method.
Make sure your target server meets the system requirements for the latest version of macOS.
If your server relies on DNS or DHCP servers, make sure they’re turned on during the process.
Upgrade your server
If your Mac uses macOS High Sierra or macOS Mojave, check for any updates for macOS. If an update is available for macOS, click Update.
Check for any updates to macOS Server. If an update is available, click Update, then open the Server app and finish setup.
Open the Server app and finish setup.
Migrate your server
You can use any one of the following sources to migrate your server data to another Mac:

A Time Machine backup
How to migrate your server data
