is it possible to migrate from open ethereum v3.x to erigon?

[donamk]

I am running three open ethereum nodes using POA.

I have searched a lot but I couldn't find an article about how to migrate and it is possible.

Is it possible to migrate from open ethereum v3.x to erigon? If the answer is yes, how can I do that?

Same question here. We have a snapshot of almost fully synced node and would like to use this as a starting point for an erigon node.

we do support trace_* rpc methods for compatibility with open ethereum
