M-appliance does not show available upgrades

[karl.dorme]

My M-160 does not show any updates available, and I'm on 6.5.3-014, so there is a newer 6 and already a 7 release ...

(in the GUI - system adminstration - system upgrade - available upgrades

It showed me the upgrades, however, before I made the upgrade to 6.5.3-014 (from 6.5.3-007)

Anyone who had the same problem ?

Open a case with Customer Support.  Sometimes IronPort forget to provision upgrade paths from certain builds.  On other occasions this may be intentional as the upgrade path has not yet been qualified.  As build 014 was a late substitution for 013 the latter may be more likely.
