8.2 Upgrade Surprises

Occasional changes to Condor can cause unexpected errors or results to users. Here is a list of changes to note and be aware of.

• We believe that Condor 7.2.x and 7.0.x are wire-compatible, and can be freely mixed between computers in a Condor pool. However, we do not regularly test this compatibility and cannot guarantee it. Therefore, we recommend using a single release of Condor when possible. Please note that although Condor 7.2.x and 7.0.x may be mixed within a pool, they ought not to be mixed them on a single computer. That is, a condor_master daemon running 7.0.x cannot run Condor daemons from version 7.2.x, or vice-versa.
