     1  # Upgrades and Migrations
     2  
     3  As new versions of Pachyderm are released, you might need to update
     4  your cluster to get access to bug fixes and new features.
     5  These updates fall into the following categories:
     6  
     7  * [Upgrades](./upgrades.md) — An upgrade is moving between point releases
     8    within the same major release. For example, between version 1.10.0 and {{ config.pach_latest_version }}.
     9    Upgrades are typically a simple process that require little to no downtime.
    10  
    11  * [Migrations](./migrations.md) — A migration that you must perform to move
    12    between major releases, such as between version 1.10.0 and {{ config.pach_latest_version }}.

    14  !!! important
    15      Performing an *upgrade* between *major releases* might lead to corrupted
    16      data. You must perform a [migration](./migrations.md) when going between
    17      major releases!
    18  
    19  Whether you upgrade or migrate your cluster, Pachyderm recommendeds that you
    20  [back up Pachyderm](./backup_restore.md). A backup guarantees that you can restore
    21  your cluster to its previous, stable state.
