Keeping WHM up to date is essential for taking use of the console's newest capabilities and avoiding any possible security issues that might come when using older software.
Before proceeding with the WHM update, you should:
Back up your complete server, ideally. If anything goes wrong during the upgrade, a Backup will allow you to restore to your previous server configuration.
Restart the DV server.
Be prepared to reinstall and/or restore from backup data if necessary.
1. Sign in to WHM.
Click the Update Now button in the top-right corner of WHM.
3. Choose Upgrade by Clicking..
4. Allow the updating procedure to finish.
5. Reboot your server once the upgrade is complete.
That's all! Your WHM / cPanel version should now be up to current.
