Big-IP - Percentage Load Balancing

Hello,

 

Currently we have two different web stacks, completely separate environments. We would like to stage code on run on one environment while running the previous code on the other. We have one virtual server that connects to a pool consisting of half one environment and half the other environment. My questions is if we wanted to use percentage base load balancing, were we sent 25% of traffic to one stack of servers and then 75% to the other. What would be the best way to achieve this?

 

Thank you for the help,
