Upgrades and Migrations¶
As new versions of Pachyderm are released, you might need to update your cluster to get access to bug fixes and new features. These updates fall into the following categories:
- Upgrades — An upgrade is moving between point releases within the same major release. For example, between version 1.9.5 and 1.9.7. Upgrades are typically a simple process that require little to no downtime.
- Migrations — A migration that you must perform to move between major releases, such as between version 1.8.7 and 1.9.7.
Performing an upgrade between major releases might lead to corrupted data. You must perform a migration when going between major releases!
Whether you upgrade or migrate your cluster, Pachyderm recommendeds that you back up Pachyderm. A backup guarantees that you can restore your cluster to its previous, stable state.
