# Upgrading PSR

Upgrading PSR is a process that may involve several steps, depending on the version you are upgrading from and to. This section provides a guide for upgrading from older versions of PSR to the latest version.

Important

If you are upgrading across more than one major version, you should incrementally upgrade through each major version and its configuration update guide to ensure a smooth transition.

For example, if you are upgrading from v7 to v10, you should first upgrade to v8 and then to v9, and then lastly to v10 while following the upgrade guide for each version. At each step you should confirm execution works as expected before proceeding to the next version.
