I notice that the "network:ha-clustering:Stable" repo for CentOS 6 now
contains Corosync 2.3.3-1 . I am currently running 1.4.1-17 . Is it safe to
just run this update? Are there configuration changes I have to make in
order for the new version to work? (If there is a document or wiki page
describing how to convert from Corosync 1 to 2, I would be happy to be
pointed to it).

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.
