[cisco-voip] Intercluster Trunks with Different CM Version

I have a setup with two CUCM 4.1(3) clusters connected via an intercluster
trunk. I need to upgrade one of the clusters to 6.1(2), but due to some
third party apps the second cluster will not be upgraded at the same time.
Are there any caveats or limitations to having disparate versions of CUCM at
each end of the trunk?

Thanks,
Adam
