Asim, 1: To locate the "Updating PS Series Storage Array Firmware" link, login using the link provided, then go the the firmware download page, once there, you will see different links to v5.0.7 and v5.1.1, select which link you need, and on the next page you will see the link.  Hint: it's on the same page as the Release notes, Fix lists, etc. 2:  Yes, once you download the "Updating PS Series Storage Array Firmware" pdf, you will see and confirme, the update path.  Once again, to get from v4.2.0 to 5.1.1., you need to first do a the v5.0.7 update:  4.2.0 -> 5.0.7 -> 5.1.1 Regards, Joe
Hi,  My respected customers have more than 10 EQL PS storages & half of them working on Firmware v4.2.0. He is requesting to upgrade the FW to the latest. I would like to ask question: can I go directly update the firmware latest v.5.1.0 "OR" I have to go step by step. I mean to say 1st I have to install v4.2.1 -> v.4.3.2 -> v4.3.4 -> v4.3.5 etc. and at the last v5.1.0  Anticipating for your response….With thanks & regardsAsim
