@moleske regarding the database migration you mentioned. I think you may need to leave the vip_offset column on the routes for some time, otherwise it might cause route creation/update failures during upgrades.

Maybe add a timebomb test to remind us to remove it in the distant future? Example:
7c322ce

I might skip the time bomb test cause it is unlikely I'll do something when it goes off. Though if others would like it I'll add it. Now that I see cloudfoundry/capi-ci#52 I'll try to actually run cats against (assuming I can actually get an environment)

I tried to claim a bosh lite but it seems to think there are none available. I left a message in the capi slack channel asking if I was just doing it wrong. I was able to create a bosh release with cloudfoundry/capi-release#419 but wasn't able to test if it deployed successfully due to the inability to claim a bosh lite. If someone else is able to give a whirl and run cats that would be helpful, or let me know how to correctly claim a bosh lite

putting back in draft as I got a bosh lite and cats is failing. wonder if it is cf networking needing this or something else going on
