Upgrading a Mendix 2.x project to Mendix 3

Is it possible to upgrade your Mendix 2 application to 3? I've tried importing exported packages, but version 2's packages are incompatible with 3.

Just open your v2 project in the version 3 Modeller - it will ask whether to upgrade it. Be sure to take a full backup before doing this as there is no reversing this process.

After the upgrade, you may also need to upgrade to newer versions of some of the widgets you use
