We use a deployment software and are able to use it successfully for all upgrades except Box Drive. This is due to the fact that there is a prompt for confirmation that the upgrade will cause loss connection and in a ticket was told there was no way to force it to continue.

What I'd like to see is a way for either through a deployment software, GPO, or PowerShell, be able to force upgrades at start-up. This would ensure that users are not yet accessing files that could be messed up.
