Windows Azure cannot perform a VIP swap between deployments that have a different number of endpoints.
We constantly get the error "Windows Azure cannot perform a VIP swap between deployments that have a different number of endpoints."
This is the worst error, you have spent a ton of time coordinating a date to do a VIP swap to release a new version and then right when you've doing the swap you get this error message and your entire promotion is ruined. All the alternatives (redeploy over production, DNS changes) are either too risky or difficult to coordinate.
We are evaluating a solution for this. Please stay tuned.

Please vote to have the current approached changed as this is a very frustraiting issue to have to deal with and coordinate around.
I have to agree, nasty behavior.

The feedback/suggestion is to make Azure allow VIP swaps when the deployments have a different number of endpoints.
