Still running 11.2.3 non-a release, but in need of updates to address a
few issues that are fixed in the Oct 2013/Jan 2014 imaging driver
updates. Namely instances of 'bad control data' failures on image
restore and support for some newer devices.

Any concerns if I update the servers/satellites, but continue devices
with the 11.2.3 non-a agent for now?

Rationale is ultimately a matter of timing -- mid-semester and a number
of deployment projects already on the go.

Ideally, I'd like to update the primaries/satellites now to keep
operations on track re: imaging then circle back on the agent this
summer, most of which would receive a new image with the updated agent
