I currently move my app code from traditional CRUD app to Axon，
now i face the situation to move the data from old app to Axon，there may be two part of work to do：
1：old data -> read store （mapping from traditional mysql tables）
2：old data -> event store
I wonder if i can only create SNAPSHOT event in event store and skip recreate domain events to simplify the job of migrate old data to event store?
