The Ubuntu server environment the 🍊 Pi Zero offers will become my replacement for Plesk, which is now $30 / month. All the virtual URL configuration files should transfer seamlessly.
I will test the environment on the 🍊 Pi Zero before moving it to a new smaller AWS EC2 instance.
I contacted Plesk support about upgrading Ubuntu to 24.04 from 22.0x to see if that version was supported. They said the upgrade isn't automatic and will need an administrator with good Linux skills. They offered to do the upgrade for $125 + tax.
In a year or so Plesk has doubled in price. The CTO left the company recently as well.
My migration to a new AWS instance running Ubuntu 24.04 and Webmin will reduce my monthly hosting cost by 70% and be on the current version of Ubuntu.
I was able to get the new OneBasic AWS hosting server running with Web/Virtualmin. The Virtualmin version of Webmin is open source and offers an enhanced version for $7.50 USD / month. Virtualmin will read Plesk site backups and migrate the sites. It feels good to be running on the latest version of Ubuntu at a 1/4 the costs of what is currently running.
