You should use a different deploy process, we currently use Fabric, it creates symlinks for certain folders so you could go back to the previous version and the shop is set to maintenance for a very small amount of time. I would recommend deploying within the hour that the shop has just a few users.
More information about fabric.
Our deploy task, this might help you:
