+You can upgrade your on-premise TimescaleDB installation in-place. This means
+that you do not need to dump and restore your data. However, it is still
+important that you plan for your upgrade ahead of time.
+
+Before you upgrade:
+
+* Read [the release notes][relnotes] for the TimescaleDB version you are
+  upgrading to.
+* Check which PostgreSQL version you are currently running. You might need to
+  [upgrade to the latest PostgreSQL version][upgrade-pg]
+  before you begin your TimescaleDB upgrade.
+* [Perform a backup][backup] of your database. While TimescaleDB
+  upgrades are performed in-place, upgrading is an intrusive operation. Always
+  make sure you have a backup on hand, and that the backup is readable in the
+  case of disaster.
