I saw humor in this article comparing VMware VMotion with Microsoft Quick Migration:
So, the best thing to do is to test the applications that will eventually run in virtual servers with Quick Migration and see what happens. Then, in a physical server with the installed application, run it and use it to perform an action. Mid-way through the process, disconnect the network cable, count to 10, restore it, and see what happens.
Is Quick Migration “good enough” for your workload? Don’t count on it.
