Migrating from Canton Fabric to Canton Postgres

Canton Network
1

Hello everyone, is there an official (or workaround) to migrating all the data from Canton on Fabric to Canton on Postgres?
I am aware of this post from 2022 where they mention using the participant.transfer functionality, but this has the limitation of only allowing one contract to be transferred at once.
Moreover, this post from January of this year implies that transferring 2 or more parties and their contracts is not feasible yet (has 2.9 changed this?).
Is there anything that can be done?

Thank you in advance.

Hi @Luis_Almeida , The data that matters is on the participants, not the synchronizer. My recommendation would be to treat this simply as equivalent to a sync domain upgrade and follow the same steps as for a protocol version upgrade. The docs for that are here: Upgrade To a New Release — Daml SDK 2.9.5 documentation
