Looks like OEL 5.6 must have come out in January 2011? Some information is here OEL 5.6 Release notes ...
Has anyone proceeded very far testing and upgrading their systems to OEL 5.6? I need to start figuring out my plan.
One of the prior OEL upgrades had a mandatory powerpath upgrade ( well at least if you wanted to use your EMC storage ) so that's one of the things I need to chase down.
I will probably do some posting eventually about my plan and how things went but would appreciate any comments/feedback from anyone farther along the OEL 5.6 upgrade path than I am currently.
