Upgrade from SEP 11.x to SEP 12.x

Hello guys,

I would like to ask you for a support.

I'm thinking about upgrade of SEP 11.x to SEP 12.x in my environment. I have couple of servers which I cannot simply reboot but they have scheduled reboots. What if I will do an upgrade to SEP 12.x and reboot will come later, for example in a week after. Do you think that this is fine? Will SEP 11 work fine until reboot? My servers are running on Windows Server 2003 and 2008 R2.

Thanks in advance, Michal.
