Personally, I would not upgrade. If you do, you will want to test 
outside of production first.

Corosync needed cman to be a quorum provider in the 1.x series. In 2.x, 
it became it's own quorum provider and cman was no longer needed. Last I 
heard upstream, pacemaker on EL6 is only supported on corosync 1.4 + 
cman. I'm sure you're not concerned about paid support, but it does mean 
that the corosync 1.4 stack is much better tested on EL6 than 2.x is.

If you really want a corosync v2+, then I would recommend switching to 
CentOS 7.
