Adopt an existing Debezium Server

Pipelines → Adopt existing: paste its application.properties. BeziSync maps tables, snapshot mode, naming, format, value formats, key columns and transforms (known SMTs become steps, any other becomes a custom step that needs its policy), keeps safe extras as advanced properties, and lists what it manages itself (connection, offsets, slot, history) with warnings. Stop the old deployment first; BeziSync uses its own slot and offsets, so choose "Only new changes" to avoid copying rows again, and drop the old slot afterwards.
