Hello everybody,

I have a simple Ecore meta-model and model instances saved to a relational database using Eclipse Teneo / Hibernate. Now, I would like to check if I can use Edapt to migrate from one meta-model version to another, including migration of my model instance data. I checked the tutorial of Edapt and also the source code in the GIT repository and am not sure if I can use Edapt out of the box. To me it seems that Edapt relies on model instances being persistet in either XMI files or a CDO repository. So I would have to write my own Migrator and/or MigrationReconstructor... Is that right or am I completely lost and there's another - much simpler - approach?

Thanks for any hints.

Cheers
Timo

Hi Timo,

your assumption is correct, a direct migration within the database is
not possible with Edapt. A common workaround is a database export to
XMI, a migration and a re-import to the database.

Cheers,
Maximilian
