We are trying to upgrade our Activiti engine from 5.6 to 5.14 … problem is in our production system, the old data in-flight data needs to be kept alive.

We only provide support for database upgrades from 5.7 onwards. Our QA is testing this.
For 5.6 or earlier we don't have these tests.
I would rely on sqlplus instead of the Activiti Explorer for the database content.
The exception you included is just a session serialisation issue, so nothing serious.
But are you experiencing real issues?

Thanks for the response! Yeah sorry abou the 5.6, we've been stuck on this for a while now.

As for real issues … we haven't yet been able to test hooking up a copy of our dev system to this copy of the 5.6–>5.14 dev db. We're planning on doing just that soon. Its just that we were hoping the 5.6 to 5.14 upgrade would have been a bit more seamless (hehe perhaps a bit desparately I guess), and was a bit dismayed that the 5.14 activiti-explorer did not seem to list of the old inflight executions or the old deployed processes. Anyway, there will be more from us as soon as we can run the test.

Just so I don't misunderstand, is the Activiti QA testing the 5.6 to 5.14 upgrade too by any chance?

No, we only have upgrade tests starting from 5.7. But you could use our upgrade tests to see if there could be issues:
