Important: When updating the Unimus server, you must also update all Unimus remote Cores to the corresponding new version. If the remote Core version does not match the server, it will fail to connect.
Using the Installer
If you installed Unimus (or Unimus Core) using our Windows or Linux installers, you simply need to re-run the installer* to upgrade to the latest version.
The installer will take care of upgrading everything as required. All data will be migrated and you will be able to use Unimus just as before.
...
If you are using HSQL (the embedded file-based DB), simply make a backup of the database directory.
Windows: "C:\ProgramData\Unimus\hsql"
Linux: "/etc/unimus/hsql"
Update sequence
Since Unimus 2.0, updates are designed to bring your Unimus instance up to date from any previous version. You do NOT need to upgrade version-by-version.
What this mean in practice is that you can upgrade directly from for example 2.1 to 2.6, and you do NOT need to deploy the inbetween in-between versions.
If you are upgrading from v1 (any 1.x.x release), you will first need to upgrade to 2.0, and then you can update directly to the latest build in v2.
