How to Migrate From EasyApache3 to EasyApache4

Here, we will teach you to use the /usr/local/cpanel/scripts/migrate_ea3_to_ea4 script to install or uninstall EasyApache 4 on the command line.

Log in to your server via SSH.
Run the following command as the root user:
```
/usr/local/cpanel/scripts/migrate_ea3_to_ea4 --run
```
Note:
- If your system runs CloudLinux™, the migrate_ea3_to_ea4 script downloads and runs CloudLinux’s EasyApache 4 migration script.
- If your system runs CloudLinux, you cannot use options (for example, the --install_profile option) with the EasyApache 4 migration script.
- If your system runs CloudLinux, you must disable the FastCGI option in EasyApache 3 before you run the migration script.
- As the migration script runs, the /scripts/migrate_ea3_to_ea4 script copies the /usr/local/lib/php.ini file to the /opt/cpanel/ea-php??/root/etc/php.d/php.ini file and to all installed ea-php versions on your server. To prevent complications, the system comments out lines that resemble the following lines:
  - extension=
  - extension_dir=
  - zend_extension-
- The system does not adjust any other lines.
- On systems that do not run CloudLinux, if you receive a message that you must install the Experimental Repository, you must install the repository with the yum install ea4-experimental command, then attempt to migrate the server again.
