We’re looking into using Event Store Replicator (https://replicator.eventstore.org) to migrate our event store to a new server.
One thing I’m not sure about is how to deal with projections. We have our “bread and butter” event stream (ie., donor-123456), and then projections that write to other streams.
While doing the migration, should we be turning off projections? If don’t, will we wind up with duplicate events?
