Here we have a cluster with Accounts/Containers ring with part power 8
and our Objects ring with part power 20 (builted later). Now we want
to migrate the 'old' Accounts/Containers ring to a new one, with higher
part power, like 20.

Is there a better way to do this? I'm doing some crazy tests with
SAIO and multiples storage nodes, based in build a new ring
with part power 20 and just swap the old files
(account/container.ring.gz) with the new ones and let the replicators
do their jobs, moving *.db files to their new home partition.

Until today these tests worked fine, but I don't know how to do it on a large scale,
with some terabytes of data. Just wondering about some ways to do that :)

And before/after this change, is there any command in swift that i can
audit this entire process, ensuring that cluster data remains the same?

Thanks!
