best way/practice to move vm from host to another

Hello,

We have esxi 6 essentials on 2 host (old one and the new one) and using vcenter i see i can migrate vm's which is great - but the vm's have to be turned off. Vreeam has the quick migration which works live, but testing it shuts off the old one and turns on the new one, which i'm fine with - but is there a way to set it do it flips the switch at a certain time so it doesn't finish during business hours and turns off?The problem is our sbs2008 vm is about 3TB and moving that takes some time moving to the new host. The smaller vm's we have i can shut down and move over with out any issues or interruptions most have already been moved over to the new host.

i'm trying to avoid any or at-least minimize any downtime.  so other than those 2 options is there something  i've maybe overlooked? first time having to move over to a new host and wanna make sure i 'f it up

Thanks
brian
