I built a complex module in Mendix Version 7.20. I actually need to being able to open it in Mendix 7.31.1. It is all default (but a lot of) Mendix microflows and pages, so I thought of saving myself some work and spoofing the Mendix version of the MPR file. Via SQLite plugin of Google Chrome I am able to update the _ProductVersion and _ BuildVersion columns of the _Metadata table to the correct Mendix version I need.:
update _Metadata set _ProductVersion = '7.13.1'; update _Metadata set _BuildVersion = '188.8.131.52';
Once I close the browser, reopen the MPR file with SQLIte and check the table, the columns are reverted to their old values….
Does anybody know how I can proceed? I know this is definitely not a best pratice, but rebuilding in Mendix 7.13.1 will take a lot of effort.
EDIT: Please be aware this is not a best practice as mentioned. You should refrain from doing this unless there is no other way and you have ample experience with the Mendix platform.
Use the Mprtool.exe in the modeler directory (C:\Program Files\Mendix\7.13.1\modeler) :)
and use Tools → Edit metadata from the menu
