You can use Remote Management Services to copy tasks from QV Server1 to QV Server 2, although:
- Not for supporting tasks
- Not automatically.
Open QMC->System->Setup->Remote Management Services and configure the other servers in your QV environment. You'll need a Publisher license for that, which I'm guessing you already have since you're managing an enterprise environment (DEV/ACC/PROD)
BTW QMC Help is your friend here. There isn't much documentation available, especially not in the QlikView Server Reference Manual
