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 a Portable version of Unimus (.exe, .jar, etc.), simply stop the current Unimus runtime, download the new release, and re-run.
For the Docker distribution of Unimus (or Unimus Core), please see the documentation in the GitHub repository.
We always recommend backing up the DB before upgrades.
If you are using MySQL of PGSQL, please make a backup (dump) of the DB using the native DB management tools.
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"
