====== Migration: nitro to casa ======

On 2026-10-13 the entire folk.zone stack moved from nitro (AMD FX-4130 desktop, ''192.168.1.67'') to casa (ThinkPad X270, ''192.168.1.85''). Nitro is now a workstation; the dormant hiatus services' data remains stored there.

===== Approach =====

  * No destructive step on nitro until casa was proven. The nitro stack stayed stopped-but-intact afterward as the rollback path.
  * Backups verified on three machines (nitro, casa, and a third machine) before any service was touched.
  * The router was the cutover switch: WAN :80/:443 port-forward rules moved from ''192.168.1.67'' to ''192.168.1.85''. DNS never changed because ''*.folk.zone'' already pointed at the public IP.

===== What Moved =====

  * The single ''server/docker-compose.yml'' stack: every service plus the shared Caddy reverse proxy
  * Named volumes rsynced across: app data, databases, the DokuWiki pages dir (this wiki is bind-mounted, so it went live on sync)
  * ''.env'' secrets copied by hand
  * The wiki, homepage source, and scripts under ''~/homelab/''

===== What Did Not =====

  * The dormant hiatus services (Mastodon, Lemmy, Forgejo, Pixelfed, BookWyrm): their configs and data stayed in ''server/dormant/'' on nitro
  * cafe's own stack (fanfiction.lol), which is a separate machine
  * A duplicate folkzone stack left running on cafe from before the migration: leftovers, worth stopping

===== Lessons =====

  * A single compose file plus named volumes meant the entire stack could be moved with one rsync.
  * The Caddyfile inode bug bit during the move: an rsync-replaced file means ''caddy reload'' sees no diff. Restart the container. See [[folkzone:troubleshooting:caddy_autosave_not_loading_config|Caddy Autosave Not Loading Config]].
  * Using a laptop as a server worked: lower power draw, a built-in UPS in the battery, and no fan noise. See [[folkzone:machines:vivobook|vivobook]] for the same approach applied deliberately.
