Reverse diff after NED migrate

Hi, I am having a problem with my services after a NED migration to a major release. If I invoke the service create method (via check-sync, un-deploy, delete, etc) I get an "Error: internal error". New services created in the new version of the NED doesn't have this problem; only old services created before the migration.

After a deep analysis I managed to identify which elements in the device configuration tree are the ones that trigger the error. The migration process modifies correctly the path according to new NED model. But I think something is wrong with the reverse config.

So, my question is:

According to Chapter 11 in NSO development manual, FASTMAP description: "When the service instance is created, the reverse of the resulting device configuration is stored together with the service instance"

When a NED migration is executed, does this reverse config is also modified? Is it possible that my service reverse config is trying to delete some elements that no longer exist in device data tree?

Thanks.
