Hello,   FYI:  The upgrade path is in the firmware upgrade instructions that's with the firmware version you want to upgrade to.    6.0.2->7.1.11->8.1.4->9.0.   Not every controller type supports 8.x or 9.x.  What model array do you have currently?  You will need to restart after every upgrade before loading the next version.  If you are running VMware ESX/ESXi you'll want to take an outage for at least the first upgrade.  There is an issue with FW < 6.0.6-H2 that can result is VMFS Datastore corruption.  It's rare but shutting down prior to the upgrade would 100% prevent it.  Given how many steps it will take, doing taking a maint window is a good idea.   Regards,  Don
