# Upgrading Swarm

The section describes how to upgrade a Swarm package or tarball installation to a newer release.

- When upgrading to Helix Swarm 2022.3 or later, ensure that you upgrade Helix Core Visual Client (P4V) to 2021.3 or later.

- In the Swarm 2024.3 release, Redis binary has been upgraded to version 7.2.4. As a result of this upgrade, the kernel and glibc requirements have automatically changed from version 2.6 to 3.10. If you need to run Redis under kernel version 2.6, you can do either of the following:

  - Compile Redis from sources on the target host meeting the target kernel.

  - Or use your own older Redis installation.

If you are not already running Swarm, none of these instructions apply to you. Instead, see the Swarm installation instructions.

Choose your upgrade process:

- Upgrading a Ubuntu package installation.
- Upgrading a RHEL package installation.
- Upgrading a Docker container.
- Upgrading a tarball installation.
