Classically, you started the Engine Configuration UI and clicked on the button <code>Convert</code>. But UI Interactions in a container world are not desired.</p> <p>I think for the container use case, our <code>autoConvert</code> feature is pretty nice. While starting the container the migration will be done automatically. See <code>autoConvert</code> in the <code>SystemDb</code> section:</p> <p><a href="https://developer.axonivy.com/doc/latest/EngineGuideHtml/configuration.html#configuration-file-ref-ivy-yaml">https://developer.axonivy.com/doc/latest/EngineGuideHtml/configuration.html#configuration-file-ref-ivy-yaml</a></p> <p>We provide additionally a Command Line Tool, called EngineConfigCLI (<a href="https://developer.axonivy.com/doc/latest/EngineGuideHtml/tools.html#tool-engineconfigcli).">https://developer.axonivy.com/doc/latest/EngineGuideHtml/tools.html#tool-engineconfigcli).</a> This CLI is also able to convert the database. This CLI tool is also available in our docker image.</p> <p>Be aware that a migration can take some time.</p> <p><strong>Attention</strong>: Always make a backup of the SystemDb before converting.</p>Alex SuterFri, 30 Aug 2019 02:06:51 -0400https://answers.axonivy.com/questions/3952/docker-migration-7-2-1-to-7-3-1/3954
