Upgrading Ontap from 7.2.7 to 7.3.7

It is always better to plan firmware update along with usual maintenance and hardware expansion downtime. You may need to upgrade to newer version of Ontap for several reasons, which may include providing compatibility between disk shelf and controller or for installation of an expansion card for new buses. I did it before adding my DAEs. You need a partner account to download correct update patch and detailed documentation. You should also have an anti static wrist band, sheets, console cable, usb to serial converter and cross cable.

There are several ways for upgrading Ontap, but the main idea remains the same, you have to update the dot version residing on vol0. First you have to mount \vol0 on a unix based server (I used RH in my case).
