Part of the LDS migration (Stufe 1): MS SQL → PostgreSQL on Azure, before infrastructure move to DFX servers. See
DFXServer/server→infrastructure/migrations/lds-migration.md.Dieser PR enthält nur den Code-Umbau. Die API verbindet sich nach dem Deploy mit PostgreSQL — die Datenbank auf Azure ist aber noch MS SQL. Ohne Infrastruktur-Vorbereitung crasht die API.
Voraussetzungen vor dem Merge:
app-lds-api-devtesten, bevor PRD umgestellt wirdCutover-Ablauf (ca. 10 min Downtime):
SQL_HOST,SQL_PORT,SQL_USERNAME,SQL_PASSWORD) auf PostgreSQL umstellenRollback:
Env-Vars zurück auf MS SQL, alten Code deployen (revert commit), API starten.
