I think we need to add explicit validation for router being set to admin state
down prior to upgrade.
This should eliminate the confusion.

Title:
migrate non-dvr to dvr case, snat netns not created
Status in neutron:
In Progress
Bug description:
On a 1+2 env, router has external network attached.
Use follow steps to migrate from non-dvr to dvr:
1) modify related config files.
2) restart related services.
3) run command "neutron router-update --distributed=True ROUTER".
Now, there's no snat-* netns create on controller node.
As a workaround, restart neutron-l3-agent on controller node will work.
And in l3-agent.log, we can find:

It seems current code is not ready to migrate LegacyRouter to
DvrRouter.
