Re: [MooseFS-Users] Access to data while upgradeing from 1.6.27 to 2.xxx?

Hi Michael,

Exactly.
You can update old MooseFS master to new 2.0, and start whole cluster
with old components like: chunkservers, clients, metaloggers.
After this step you can start one by one update for other MooseFS
components under running MooseFS cluster.
