Stackify agent updates can sometime require restart IIS or rebooting of the server. To ensure that this event don't happen when the server in under normal usage, it would be nice to be able to configure a windows where updates are applied without impacting users of the server. Ideally this would need to be a particular time window on certain days of the month. For example, we usually do server maintenance at 11pm on the last Saturday of the month but it probably needs to be easy to adjust in case of public holidays, etc
Another option that might be easier to implement and safer would be the ability to update Stackify on many servers at the same time. For example, they would all be configured as manual but during the server maintenance window, they could select some or all of the servers running Stackify and click a single button to launch an upgrade on all of them.
