[CentOS] GFS version compatibility

Can a GFS 6.0 and GFS 6.1 system share the same storage?

I'm considering building my system using GFS 6.0 and then migrating up to
6.1 when it is more stable.  I would prefer to migrate the machines one by
one to avoid any overall downtime, but this would mean that some nodes would
be 6.0 and other nodes would be 6.1.  Will this work, or would I need to
take everything down and migrate all of the nodes at once?

Is there a better place for this question?
