Hi all,

Yes, once the oslo.db initial release is cut, we expect the migration
from using of its oslo-incubator version to a library one to be as
simple as following the steps you've mentioned. Though, we still need
to finish the setup of oslo.db repo (AFAIK, this is currently blocked
by the fact we don't run gate tests for oslo.db patches. Doug, Victor,
please correct me, if I'm wrong).

Thanks,
Roman
