Please note, the issue is for Rolling Upgrades using Remote Store method available during DG lifetime.

UPDATE: As there is a new migration property , with it specified the migration from DG 8.5.5 and 8.4.8 works properly. But for other versions I am still getting and exception:

*For Rolling upgrades from DG 8.1.x - DG 8.3.1 : *

In this case the migration fails in all cases. Please find attached the server log : 8.3.1-8.6.server.log

*For Rolling upgrades from DG 8.0.1: *

Here again all caches migration fails but with some kind of other exceptions. Please find attached: 8.0.1-8.6.server.log

You can find the reproducer here: https://gitlab.cee.redhat.com/dg-qe/dg-qe/-/tree/master/scripts/rolling-upgrades?ref_type=heads

For running it, download DG 8.6.0.nightly build and the version of the server which you need for testing, and the run the following command:

bash -x ./do-rolling.sh -s /path/to/source/server/ -t /path/to/8.6.0/server/

In case of successfull run you will find in logs the following lines (mixed with other logs):
default cache - TEST PASSED
eviction cache - TEST PASSED
protobuff cache - TEST PASSED
