      CTA Catalogue Schema Issues 10m

      Restore of CTA Catalogue in PPS

      • See #659 Restore preproduction database

      CTA Catalogue upgrade in PPS from 4.5 to 4.6

      • Forget v5.0 schema, move v4.6 schema to master

      Next CTA Schema Version

      • Skip 5.0 and make next schema version v10 to avoid confusion

      Compatability of CTA software versions to CTA schema versions

      • The confusion of "backwards compatible" and "non-backwards compatible".
      • Order of upgrades (software first/schema first?)
      • A simple and comprehensible scheme to map compatability of CTA software versions ←→ CTA schema versions.
      • The problem of upgrading the DB for 3rd party sites (e.g. inserting new columns with NOT NULL constraints). Add a "no new constraints" option to the upgrade scripts?
