The author migrated their blog from an outdated Ubuntu 16.04 server to a new FreeBSD server on Hetzner, motivated by the need for security updates and a desire to try something new. The old server had been running for 10 years and was no longer supported. The author set up a new stack using FreeBSD, Jails, and Caddy, and migrated their sites to the new server. The process involved creating Jails for each site and configuring an internal virtual network.
