The error already tells you most you need to know:
The module MPK needs to be at least 8.12.0 in order to be able to be used in Mendix 9. To upgrade your module:
- If you still have the original project you exported it from; you can upgrade that project to at least 8.12 and export again
- If you don’t, you can import the module in a new 8.12+ project and export again
After that you should be able to use the module MPK in mendix 9.
Hi Niraj,
Take a backup of 8.10.2 version application.Upgrade this backup app to 9.x version From this upgraded app,export the module you want,then import the same to your 9.x version.
Test it,give a try. It's just my suggestion.
