How to downgrade the cPanel/WHM version?
Many of our clients asked us how can they downgrade the cPanel/WHM version of their server. Officially cPanel/WHM doesn't offer to downgrade the cPanel/WHM version. So if you wish to downgrade the cPanel/WHM version of your server, you need to edit a file and replace the cPanel/WHM you would like to downgrade. You can call it, a trick. Let's start!
Run the command to check the current version:
cat /usr/local/cpanel/version
Output is:
11.88.0.2
If you wish to downgrade the version to 11.86.0.20, run the command:
nano /usr/local/cpanel/version
And replace the version and save it.
Also, modify the file /etc/cpupdate.conf, output below:
CPANEL=11.86.0.20
RPMUP=daily
SARULESUP=daily
STAGING_DIR=/usr/local/cpanel
UPDATES=daily
Now, update cPanel/WHM with force:
/scripts/upcp --force
Wait a few minutes, once the downgrade will be completed, run the license update command.
