This question gets asked every few months. 

It is not recommended to perform an upgrade with ISSU or FSU/eFSU because if it does not work, it will fail very spectacularly.  Another reason why ISSU or FSU/eFSU is not recommended is because ISSU or FSU/eFSU does not support ROMMON upgrade.  

IMPORTANT:  Read the Release Notes if the ROMMON needs to be upgraded or not.  When in doubt, always upgrade the ROMMON!

A good guide on how to upgrade the switch (in VSS), including ROMMON, can be found HERE.

Here is the compatibility matrix:

You cannot directly jump but can go via multiple jumps.
