MIM Maintenance recommendation - at SYSPLEX or LPAR level?

Products

• MIM Resource Sharing (MIM)

Issue/Introduction

I am about to rollout MIM 12.5 current maintenance (approximately 2 years of maintenance)

What's the recommendation ? should I rolled out at LPAR level or SYSPLEX level?

Environment

Release : 12.5

Component : MIM

Resolution

We do not have a specific recommendation regarding rollout of maintenance, whether per system or MIMplex. 
We do not have any fixes that require the fix to be applied on all systems simultaneously. If that was the case, we would include HOLDDATA noting that requirement.

Older and newer maintenance levels of the product are compatible within the same MIMplex.
