Yes, you can go directly from 7.3.x to 8.1 (check release notes and update guide for prerequisites). Do you have any reason to update at all? Any specific functionality that is missing? Have you ever heard “never touch a running system”? ☺

8.x is more resource demanding, so 7G may be better choice on low end systems unless you need some features missing in 7G.

If system is correctly configured for failover, it can be done as NDU without downtime. CIFS and NDMP sessions will be interrupted though.

Why 8.0.1? I would say, either 8.0.3 latest patch or 8.1.1P1. What is the reason to chose this specific version?

Current NVRAM size 4GB which is causing some performance impact , is there a way to Increase the NVRAM so that we can have smooth functionality .

Sadly NVRAM is a fixed size per controller so you have only really two options, buy a head upgrade to FAS3200 or get a second HA pair of FAS2200. C-mode could be an option but you have to flatten your current 7-mode box to change ONTAP flavour

Regarding the 'resource demanding' quote, check out these posts before upgrading to DOT 8.1

Also, probably look at 8.1.1P1 rather than 8.1.
