Upgrades and Migrations¶
As new versions of Pachyderm are released, you may need to update your cluster to get access to bug fixes and new features. These updates fall into two categories, which are covered in detail at the links below:
- Upgrades - An upgrade is moving between point releases within the same major release (e.g. 1.7.2 –> 1.7.3). Upgrades are typically a simple process that require little to no downtime.
- Migrations – A migration what you must perform to move between major releases such as 1.8.7 –> 1.9.0.
Important: Performing an upgrade when going between major releases may lead to corrupted data. You must perform a migration when going between major releases!
Whether you’re doing an upgrade or migration, it is recommended you backup Pachyderm prior. That will guarantee you can restore your cluster to its previous, good state.
