Hi,
We always make changes in the model ; so it happens very often that the data which is already stored has to be migrated the next time the app starts.
There should be a way in Mendix to define a microflow executed automatically when the database change is applied to the model. It should also be possible to review all migration microflows for Administrators;
In a nutshell, we need LIquibase (https://liquibase.org/) for Mendix.
Cheers,
