It is only internal implementation changes.

That's not entirely true, is it? There are config variables to change and it opens up the possibility of a scenario that the operator may not care about.


If we were to remove the non-pluggable version altogether, then the default for ipam_driver would switch from None to internal. Therefore, there would be no config file changes needed.

I think this is correct.
Assuming the migration path to Neutron will include the data transformation from built-in to pluggable IPAM, do we just remove the old code and models? On the other hand do you think it might make sense to give operators a chance to rollback - perhaps just in case some nasty bug pops up?

They can always revert to a previous release. And if we enable the new implementation start of Newton, we’ll have enough time to fix bugs that will pop up in gate.

What's the team level of confidence in the robustness of the reference IPAM driver?
