Moving to a new server¶

Prepare: keep the recovery key off the machine, add a backup target, and set the A record's TTL to 300 s or less. Devices keep their links.

# on the new server, after bootstrap.sh
sudo morzer --product dotdash installation import --from-backup \
  --target s3://bucket/dotdash --credentials-file ./bucket.yaml \
  --identity ~/dotdash-recovery.key
sudo morzer update oci://ghcr.io/morzecrew/dotdash:stable
# optional, keeps Caddy's certificate (import prints both ids)
sudo morzer backup fetch <backup id>
sudo morzer restore --force --confirm <installation id> --identity ~/dotdash-recovery.key

Then point example.com (and ns.example.com) at the new IP and shut the old machine down: two live servers with one installation id confuse each other's backups.
