I'm not sure they had completed the migration to v3 at that point and it was still a mixed v2/v3 setup. Pretty sure by 21.04 it was all v3. While I do find upgrades to a new version can be very disruptive if it is left for a few versions, updates to the next version has been minimally disruptive for me. I guess a lot depends on how much 'extra' stuff you install and what tweaks you do, but for the last few years, I've found the upgrades quite painless. A lot depends on what changes - for example, I expect the update to 22.04 or maybe 22.10 will be more disruptive due to the move to pipewire for sound. One thing I do find useful is to upgrade a virtual first. I use virt-manager to create a virtual machine running my current version and then upgrade that to see how the upgrade goes. In fact, I tend to maintain a VM which is the same as my current version and whenever I need to make some potentially disruptive upgrades or configuration changes - such as updating org to a new version or try out the latest Emacs, I do that on the virtual machine first. This way, I don't interfere with my core system and configuration and have time to investigate any issues before doing the same on my core system.
