I'm preparing for a shelf firmware update with 2 stacks, one with 2246 and another 4243 I think are all IOM6 modules. I need to upgrade in order to migrate ACP from OOB to In-Band but wanted to know what risks I pose to a production system. I've only updated non production shelfs so obviously there was no issues but the stakes are higher now.
Anyone have issues or any gotchas i.e. an out of date disk firmware below that of the shelf etc.
