Upgrade Steps
Please refer to the Upgrading documentation page
Patch Sets
Patch Sets are often provided containing only the files that have changed between the immediately previous release and the Patch Set Version. We provide these to make updating both quicker and easier for those of our customers who stay current and up-to-date with the latest WHMCS releases. By including only the changed files, patch sets have less files to upload which makes the upgrade process quicker and simpler for you to perform.
Steps to Apply a Patch Set
IMPORTANT: Before you begin please ensure you are running the version required by the patch. Patch Sets contain only the files that have changed between the previous release and the Patch Set Version. Therefore they should only be applied if you are running the immediately previous version.
The previous release version that these patch sets are designed for is clearly indicated as the first and smaller number in release notices providing the patch set download link.
- Download the patch set
- Unzip the patch set files
- Upload the files to the root directory of your WHMCS installation
- Visit the admin area of your WHMCS installation to trigger the version number bump and complete the process
No install or upgrade process is required.
How to Confirm a Patch Set Applied Correctly
To confirm a patch set has successfully applied, login to your WHMCS admin area and check to make sure that the Version Number displayed either on the admin homepage (in the sidebar of all default templates) or in Help > Check for Updates is the version you attempted to apply. If it has not incremented, then one or more of the files has not uploaded successfully. You should double check file permissions and attempt the steps again from the beginning.
Troubleshooting
What to do if you get a Down for Maintenance or Upgrade in Progress message after uploading a patch set
If after uploading the files from a Patch Set you see a "Down for Maintenance" or "Upgrade in progress..." warning message then this indicates that the patch set files you attempted to apply were not compatable with the version of WHMCS you were running. To complete the upgrade you will need to download the latest [Full Release] version and upgrade using the regular upgrade process as described above.
