There are no tools to migrate in either direction between EC and Replica. You can't even migrate an EC pool to a new EC profile.
With RGW you can create a new data pool and new objects will be written to the new pool. If your objects have a lifecycle, then eventually you'll be to the new pool over time. Otherwise you can get there by rewriting all of the objects manually.
