Absorbs the Cloudron server-migration material from co-op/runbooks
(now archived) so there is a single public operator documentation
repository. Files move into migration/ (plan, DNS change sheet,
pre-migration state) and provider-pricing/ is kept as its own section;
the merged README replaces both.
History is preserved: this is a merge of the unrelated histories, so
co-op/runbooks' 26 commits remain reachable from this repository and
git log -- migration/ shows their real authors and messages. File
contents are byte-identical to co-op/runbooks (blob hashes unchanged).
The cutover finished 2026-11-02 and this repo is public and read by members, so leaving a plan that reads like outstanding work is actively misleading. A dated banner now says it is complete and retained as the record; the STATE OF PLAY section is re-labelled as pre-cutover and marked superseded, with the one part known to be wrong (Listmonk's mail path, which moved to Scaleway TEM) named rather than silently corrected; and both files point at where live knowledge now lives — the cloudron-ops skill for procedure and co-op/docs/infrastructure.md for the member-facing description.
They were published to co-op/runbooks for member review, so the README's own 'Private: these contain...' line was both wrong and the first thing a reader saw. Also records the DNS sheet's wildcard caveat up front, and says explicitly that this repository is the source (no private copy).
Pre-flight, ordered cutover, post-restore verification, rollback, and the list of what Cloudron's backup does not cover. Written from a live inventory of the server on 2026-10-29; open unknowns are marked rather than guessed.
