The upgrade path in the matrix suggests i can upgrade to any of the recent 6.1(4)x updates.
The trouble is, there seems to be no clear way to determine if a release is stable/relatively bug free. I had already downloaded and merged the "6.1(4)SU1" ISO files. However, i now note that an even newer upgrade "6.1(4a)SU2" is available. Can anyone shed light on the naming convention of these upgrades (4) (4a) (4 SU1) etc... Also - is the latest release necessarily the one i should install?
Im going to install and test an upgrade in our lab first, and was going to use 6.1(4)SU1......
