Hello,   You would need to go to 8.1.x first, restart then you can upgrade to 9.0.x.     Regards,  Don  
Hi, I have two PS 6210X units sharing a RAID6 storage pool. Both units are currently running FW 7.0.4 and i am looking to get them up to the latest version. I am seeing on conflicting information about the upgrade paths. Can i go directly to V9.0.3 or do i need to go to 8.1 > 9.0.3 Thanks in advance.
