Migrate PostgreSQL clusters from the Zalando postgres-operator (acid.zalan.do `postgresql` CRs, Spilo/Patroni, WAL-G) to CloudNativePG (CNPG) on Kubernetes, incl. fully air-gapped clusters. Core knowledge: the two walls (Spilo↔CNPG glibc/collation divergence that corrupts physically-copied indexes; WAL-G↔Barman archive incompatibility that strands old backups), three migration paths (logical replication default; initdb.import for small DBs/PG≤13; pg_basebackup as the discouraged same-major…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# postgres-operator-cloudnative-pg-migration Migrate PostgreSQL clusters from the Zalando postgres-operator (Spilo + Patroni) to CloudNativePG with data intact, indexes trustworthy, backups restorable at every phase, and no dependency left on maintenance-mode artifacts. Facts below were verified 2026-07-24 against primary sources (both operator repos at HEAD, release manifests, maintainer statements); re-verify anything version-gated before relying on it in a later year. Version anchor (2026-10-27): Zalando v2.0.3 (Spilo-18 4.1-p2, PG 14–18; v2.0.0 and v2.0.1 are both defective), CNPG 1.30.1 (2026-09-23; PG 14–18; 1.29 EOL 2026-09-29, 1.31 due ~Dec 2026 — target 1.30.x), plugin-barman-cloud v0.15.1. ## Why this migration exists Zalando's operator runs on one sustained maintainer in confirmed low gear (#2921) but is not dead — the v2 line shipped PG18, dropped PG13, and flipped both `kubernetes_use_configmaps` and scram-sha-256 on by default. CNPG runs ~7× the human commit volume across three maintained lines and has a documented migration wave. **This is strategic, not an emergency**: v2 extends the safe-to-stay horizon well past the old ~2027 estimate, and …

How to install
mdr add air-gapped/skills/postgres-operator-cloudnative-pg-migration@sha256:85c6b58877adbf5bThe line at the top of this page pins the label git:20261027.249de47, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
