Wide telemetry tables become harder to maintain as oilfield instruments and indexed columns accumulate. This guide shows how to migrate a TimescaleDB hypertable to a narrow schema with a separate tag metadata table, without re-ingesting historical readings or breaking existing dashboards. It covers descriptor validation, resumable time-slice backfills, post-load indexing, compatibility views, dependent-object migration, and verification. The result is a more scalable schema that preserves history while allowing the transition to happen in controlled, reversible steps.
