Aggregate changed: How to handle snapshot store

[trancefreak77]

EventFlow has the concept of event upgraders when a new version of an event looks different. Is there also a concept with regards to the snapshot store?

If a new version of an event needs to be implemented the aggregate may also change. I am using the EF Core snapshot store implementation. Do I have to delete the snapshot store in this case? How can I repopulate the snapshot store?

Is there an existing concept / solution for this kind of issue?

Regards,
Christian

Hi @trancefreak77 you can implement a ISnapshotUpgrader to upgrade your snapshots
