Perhaps you should use replicate, even if it's only temporary. Let's
say you start with pure distribute, like this.
First you turn one of those bricks into a replica pair.
Then you self-heal on brick1, migrating data from brick1old to
brick1new. Finally, you remove brick1old.
Repeat the process for brick2 and brick3. There will be a brief
disruption each time you modify the volfiles, but most of the data
migration (which takes up most of the time) can happen while the system
as a whole is live. You can even do the replication server-side, to
avoid copies over the network.
