Upgrading P4 Code Review

The section describes how to upgrade a P4 Code Review package or tarball installation to a newer release.

If you are not already running P4 Code Review, none of these instructions apply to you. Instead, see Install and upgrade P4 Code Review.

A package installation or upgrade automatically ensures that you have a supported version of PHP. It will be the minimum supported version, and you then have the option of using a different supported version.

  • When upgrading to P4 Code Review 2022.3 or later, ensure that you upgrade P4 Visual Client (P4V) to 2021.3 or later.

  • In the P4 Code Review 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.
