If you currently use a WHMCS version that is past its End of Life (EOL) date, we recommend that you update WHMCS as soon as possible. We always recommend that you update WHMCS regularly and remain on a supported WHMCS version. This ensures that you receive all bug fixes and security updates and allows WHMCS Technical Support to easily assist you with problems.

We currently support the following versions of WHMCS:

These releases are in the Active Development stage of our development cycle. All prior versions have reached End-of-Life (EOL) and we no longer maintain them or release updates for them, regardless of the reason. If you currently use an EOL version of WHMCS, we recommend updating to a supported version as soon as possible.

Preparing to Update from an EOL Version #

Whenever you update WHMCS, we recommend that you perform steps first to prepare for a successful update. This includes:

• Ensuring system compatibility.
• Checking compatibility with any customizations or third-party modules that you use
• Backing up your database.
• Performing the update in a testing environment.

EOL Version System Requirements #

When you update through multiple versions, make sure that you meet the system requirements for each intermediate version. You may need to stop between versions in order to update for new requirements.

• If you will use the Automatic Updater tool at Utilities > Update WHMCS, make sure that you meet our Automatic Updater requirements.
• We only document selected information from WHMCS 7.10 and earlier, in order to facilitate updating from very old versions. If you do not see requirements for all of the necessary versions for your update or if you need additional information, contact WHMCS Technical Support.

Your system must meet the following requirements:
