I was recently told by a TAC engineer that if the non-boot partition contains an image that requires a stepped upgrade then you must follow the stepped upgrade procedure even if the controller is already running a newer version of code that doesn't require a stepped upgrade on the boot partition.  For example: Controller running 6.1.2.1 from partition 0 has 5.0.3.0 installed on partition 1.  Can an upgrade to 6.1.3.2 be performed directly to partition 1 since the controller is actively running 6.1.2.1 from partition 0 or does partition 1 need to be upgraded to the latest 5.0.4.X code first and then to 6.1.3.2?

I can't confirm 100%, but I don't think TAC was correct on that one.  What's in the non-running partition should be irrelevant.  You should be able to just load 6.1.3.2 into partition 1 and be done with it.

Thanks Mike!  That was always my understanding as well and I've never had an issue performing upgrades that way. 

No, you don't require stepped upgrade.

I wonder in what context TAC recommended that? Were you facing any issue and TAC recomended it or was it just a general query?

I was having issues upgrading but it was due to lack of flash memory and had to have TAC go in and clear out an image stuck in flash from a failed upgrade.  I can't say for certain because I've had that issue a couple of times recently but I believe this was the case # 1302516.
