Migrate to new nodestore

We have a pretty beefy Ceph cluster so i was thinking of experimenting with GitHub - kanadaj/sentry-s3-nodestore: A Sentry extension to add S3 as a NodeStore backend. , moving our data out of postgres. Is there any info or docs on how to migrate the data to a new nodestore? I imagine it could be done with a simple python script.

@fpacifici @untitaker any pointers for this?
