I am not sure if I missed it on the announcement and previously i haven't thought about his right away after the announcement.
How much time pass between "Appian Version announcement" and "Customers been able to schedule the upgrade" ?
I have to say I would like to see this somewhere in a documentation page.

They announced the official realase of 19.1 is on 2/22/2019. If you're on premise I assume you can start the upgrade at that time. For cloud they roll it out gradually across clients, but I am not certain of how the process is run. We are on cloud and have requested being toward the beginning of the cloud rollouts and they did so for us.
