This script makes it very easy to migrate an entire DNS zone from one AWS Route53 zone to another. This script expects you to have downloaded the old zone file via the AWS CLI to a json file called DOMAIN.zone.json. It uses the AWS CLI to perform the request, so make sure that your credentials are properly configured.
#!/usr/bin/env ruby
require 'json'
# This is the json output of the old zone, fetched using the AWS CLI.
zone = JSON.parse(File.read('DOMAIN.zone.json'))['ResourceRecordSets']
new_zone_id = 'NEW_ZONE_ID'
# We don't want to migrate the SOA and NS records from the old zone.

Ubuntu Desktop 20.04 with mirrored ZFS boot drive

Ubuntu 24.04

From the comments: "These exact instructions are not working on Ubuntu 24.04. Ubuntu has changed the naming of ZFS partitions, partition 2 and 3 are switched around, and the boot/efi folder is now different."

I don't have my dual-disk test system any longer, and so can't adjust these steps myself.

Overview

Ubuntu Desktop 20.04 supports a single ZFS boot drive out of the box. I wanted a ZFS mirror, without going through an entirely manual setup of Ubuntu as described by OpenZFS in their instructions for Ubuntu 20.04 and instructions for Ubuntu 22.04
