Upgrade Ubuntu AMI version from 16.04 to 22.04

Hello there,

Firstly, you cannot jump from Ubuntu 16.04 straight to Ubuntu 22.04 as you would need to go through each major release one by one:

16 -> 18 -> 20 -> 22

Secondly, you can create a new Ubuntu latest version instance and migrate your data by detaching the EBS volume from the Ubuntu 16.04 ec2 instance and attaching it to the newly created Ubuntu latest version ec2 instance.

The following documentation helps with the data migration:
