How to mantain Display Suite configurations when updating Drupal core to 8.3.0?

I'm recently trying to update my Drupal site from 8.2.7 to 8.3.0.
The site uses Display Suite and Bootstrap Layouts modules, both requiring the Layout Plugin module.

After several attempts, I was forced, before the update, to uninstall Display Suite, Bootstrap Layouts and Layout Plugin modules and then, after core update, to activate the new experimental core module Layout Discovery (incompatible with Layout Plugin), before reinstalling the updated Display Suite and Bootstrap Layouts modules.

The drawback of the uninstall+reinstall of Display Suite is the complete loss of any configuration specific to this module (Layouts for nodes, etc.).

There's a way to mantain such configurations between updates?
I've tried exporting whole configuration before the update and importing later, but the saved configuration is impossible to apply after update, due to incompatibilities between different module versions.

Thanks for any help.
