Hi all,
When persisting a session, process instance or workitem, Drools persists
some parts of the state as byte arrays.
I am trying to upgrade from 5.1 to 5.3 and I have some existing
sessions/processes persisted in the database. I am wondering if it is safe
to upgrade? Will the bytearrays created by 5.1 work fine with 5.3?
Is there any document describing persistence compatibility between versions?
I don’t see much in the “new and noteworthy” in relation to persistence.
Thanks.
Keep up the good work!
Best regards,
Michal

Hi again,
Anyone? It would be nice to get a confirmation that migration of persisted
session/processes is not possible when upgrading Drools.
Thank you!
Best regards,
Michal

Hi Michal,
I'm not aware of any changes.. but we need to check with mark and kris for
the timers stuff that now are being persisted.
My gut feeling is that usually if you are playing with binaries it's very
difficult to keep that compatible with old versions. Also you mention that
you are moving from 5.1 to 5.3 right? It's at least 6 months of changes.
My two cents..
Cheers

I believe there is binary compatability kept for jBPM. Kris can
provide
more details.
Due to the extreme complexity of rule persistence, we have not
maintained previous version compatability. Going forward from Drools 5.3
we will make sure that migration is always possible.
It is possible to migrate Drools (rules) 5.2 but you'll have to hack
your own script, look at the OutputMarshaller and InputMarshaller for
5.2, you can use those to make a migration helper class. Going forward
for 5.3 we will take care of that for you.
Mark
My two cents..
