6. Verify Zigbee devices are still paired and communicating
7. Decommission old VM
**Note:** ha1 currently has 2 GB RAM, which is consistently tight. Average memory usage has
climbed from ~57% (30-day avg) to ~70% currently, with a 30-day low of only 187 MB free.
Consider increasing to 4 GB when reprovisioning to allow headroom for additional integrations.
**Note:** ha1 is the highest-risk migration due to Zigbee device pairings. The Zigbee
coordinator state in `/var/lib/zigbee2mqtt` should preserve pairings, but verify on a
non-critical time window.
