I have to agree that there are two areas which really need some attention:

1. nova-volume to cinder-volume - to date there is no automated migration
of the database contents as far as I've seen
2. nova-network to quantum - nova security groups and all defined networks
do not migrate. The trouble with this migration is that there are too many
variables that are particular to the deployed environment - do your nova
networks need to become provider networks, shared networks, external
networks, tunneled networks, etc.

If anyone has done some work to automate the migrations I'll be happy to
collaborate and contribute as I have another Essex -> Grizzly upgrade
happening soon, and the Folsom->Grizzly upgrade was rather laborious due to
the nova-network->quantum migration.
