Upgrade Steps

Upgrading WHMCS is easy. To upgrade to V5.0, simply follow the steps below:

1. Begin by taking a backup of your database using a tool such as phpMyAdmin
2. Now download the latest WHMCS version either from our client area (http://wiki.whmcs.com/Upgrading#Downloading_the_Latest_Version) or from your web host license provider
3. Next, unzip the contents of the WHMCS zip file download to a folder on your computer
4. Now if you have customised your WHMCS admin folder name, you should rename the admin folder in the new files to match
5. Upload the new files to your existing installation folder replacing any existing folders & files
6. Visit the admin area as you normally would to login and you should then see the upgrade script
7. Accept the license agreement
8. Tick to confirm once you have backed up your database, and then click the upgrade button
9. Once the updates finish, delete the install folder from your server

These steps can be used to upgrade from any version of WHMCS from V3.3 & later.

Remember: After upgrading, your browser may still display cached versions of the previous files. So if you get any display issues or inconsistencies, always try clearing your cache first, both in your browser, and the WHMCS templates cache (templates_c folder files)

The upgrade is now completed. The only thing left to do is update your custom templates if you have any with the new and changed template files for the new version. See below for details.

New Language File Lines

If you are using a custom language file, then the new language file lines introduced in Version 5.1 can be found below the "# Version 5.1" line in each language file.

During the beta we will be reaching out to our known translators to convert new lines into the other languages. However if you are able to help in contributing even just some of the new lines translated, then it would be much appreciated.

Release Notes

• Display Problems/Browser Cache - Always clear your browser cache, or perform a hard refresh after upgrading, most display related issues are purely due to seeing an old version of the CSS
• New Domain Registrar Sync Cron - Until now, each registrar has had it's own sync file. But as of V5.1, the individual sync files are replaced by a single cron file (/crons/domainsync.php) which needs to be configured to run periodically - we recommend once per day. All previous sync cron commands should be deleted/disabled.
