Though we have some sysplex here, we are not yet taking advantage of rolling IPLs. We cook on our sandbox, then cook more on a first-run subset of development systems, plus, insanely, one production system, and then, more insanely, hit all remaining systems. Altering this process is an uphill battle... In a past life as a service provider, I witnessed many customers successfully use rolling IPLs with anywhere from 1 week to 1 month in between. The caveat of co-requisite maintenance or "step-up" maintenance is rare, but requires vigilance. Now that I've been in a JES3 shop, I've learned that rolling IPLs can be compromised with a Global Warm-Start.
