We're trying to figure out if it's possible to migrate from a classic
spooling mechanism to a berkeleyDB method, in order to allow us to
implement shadow failover.
We hope to do this as part of an upgrade from 6.0u8 to 6.1u3.
I found this thread in the mailing list archives - but there was not
final outcome posted. Does anyone know if it's possible to migrate from
a classic spool setup to a BDB, and if so - how?
