Migrating a site with plugin data tracked to a different instance of Matomo

Hi, my organisation currently hosts 2 different instances of Matomo. Both instances have some premium features enabled. We are interested in merging both instances to create one Matomo instance for the entire organisation.

At first I have tried using the Migration plugin, but it currently does not support migration of premium plugin data.

I have also tried manually increasing the primary keys in the database of one of the instances, in order to dump one db into the other without causing any conflicts, but this has lead me to displaying either partial plugin data, or no plugin data at all.

I have been searching for an ERD of the database (including tables of premium features) or an alternative solution, and would be happy to hear if anyone might be able to help me.
