Decommission the old Plex VM

Browse Source 
Plex has run as a container on the Docker host since the 2026-09-16
migration. The old Debian 11 VM (10.100.0.24) is now retired per
plex-docker-migration.md section 9, steps 1, 2 and 4-7:

- removed from the Veeam "Backup VMs" job
- guest shut down gracefully, pre-migration snapshot removed and
  consolidated back to Plex.vmdk
- Guacamole "Plex SSH" connection deleted
- .24 / 10.50.0.31 DHCP leases released on the UDM

The VMDKs are deliberately kept until ~2026-10-15 so the VM remains a
one-command rollback; step 3 stays open until then.

Before powering the VM off, every integration was re-verified as
pointing at 10.100.0.35: Sonarr, Radarr, Tautulli, seerr, Uptime Kuma,
Homepage, Traefik and the UDM PLEX port-forward.

Section 9 gains a decommission log recording two behaviours that cost
time to work out: Veeam turns a removed job include into an explicit
Exclude tombstone rather than deleting it, and a plain sqlite3
integrity_check on a Plex library DB fails with "unknown tokenizer:
collating" because the stock binary lacks Plex's FTS collation - that
is not corruption.

ESXi port-group counts corrected (LAN_100 7->6, DATA_50 4->3), verified
by counting NICs on powered-on VMs.

# Plex Media Server
> **Migrated to Docker 2026-09-16.** Plex ran on a dedicated Debian 11 VM at 10.100.0.24 until that OS reached LTS EOL (2026-08-31). It now runs as a container on the [Docker host](docker.md). The old VM still exists, powered on but with `plexmediaserver` stopped and disabled, as rollback. Full procedure: [plex-docker-migration.md](plex-docker-migration.md).

> The old VM is **powered off** with its disks intact (`[NVME_1] Plex/Plex.vmdk`, 128 GB) and is scheduled for deletion ~2026-10-15. Until then, rollback is: power the VM on, `sudo systemctl enable --now plexmediaserver`, and repoint the UDM `PLEX` port-forward to 10.100.0.24. Its `.24`/`10.50.0.31` leases have been released and it is no longer in the Veeam `Backup VMs` job. A verified copy of the pre-migration library DB is at `/mnt/share/backups/plex-migration-2026-09-16/`. Full procedure: [plex-docker-migration.md](plex-docker-migration.md).
