We tried to do this for a cut over and found the gear was still choosing to forward traffic to the disabled VLAN. So we ended up having to delete the IP and then add it back when we where ready to bring a building online.
This was a while back, I think summer of 2015. We felt it was a bug and talked about reporting it but I do not recall if we did, and I do not know if the functionality with this was improved.
Thanks,
