I am using 6.3.1 version on my machine. I want to upgrade it to latest version. Can anyone please suggest the steps to accomplish it. Do I need to directly install latest version? Will it not override the existing local project details or data? If I take the back up and then copy again to MENDIX folder will it show with latest version? For that also I need open internet connection? Are there any release note for the Version Release?
Install the latest version of the modeler and then with this version open your existing project.
Then go through possible upgrade steps and fix issues (if any).
If you want to keep your 6.3.1 version then you can export the project and import it into the latest release.
The release notes can be found in the app store where you download the latest release.
