Of course we'll add support for upgrading from one OVN version to another. It's not there yet. (I'll note that OVSDB has pretty good support for upgrading databases. We'll probably use that.) > 2) As a workaround, I started the OVN with empty DB and populated everything > from scratch, which works fine.

I can believe that there are bugs right now. I'm working on writing end-to-end tests for OVN; I suspect that those will fix many bugs, and prevent many more new bugs from ever getting into OVN. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
