[rules-users] drools persistence contract

[Michal Bali]

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
