Upgrading the Mendix Version of an App
Upgrading the Version of Your Mendix App
Upgrading a Mendix app can take two forms;
- Upgrading inside the major version
- Upgrading to a new Major Version
Mendix releases a new major version every year. When picking a version of Mendix to build you app in, make sure it will be released in a MTS or LTS version of Mendix. You can see the current LTS and MTS versions here on the LTS/MTS tab (https://marketplace.mendix.com/link/studiopro/) and the release schedule for them here (https://docs.mendix.com/releasenotes/studio-pro/lts-mts/).
Upgrading Inside of a Major Version
This should be fairly simple. Download the Mendix Modeler for the version you want to upgrade to. Open your app in this version and there should be no issues. If there are any issues: it will give you prompts on what to do.
NOTE: If you upgrade the app version, you will not be able to edit the project in the older version of the modeler. This will matter if there are multiple individuals on the same project. Mendix Project version and Modeler version are tied together.
Upgrading To a New Major Version
When Mendix releases a new major version, they create a guide for how to upgrade your app. For example, when Mendix 9 was released, the css system was reworked and required conversion for old projects. Here is the link for the Mendix Upgrade to 9. Look for similar guides when upgrading to new releases after this tutorial is out of date. https://docs.mendix.com/refguide/moving-from-8-to-9/
