Softaculous is an auto installer for cPanel that has 266+ scripts that auto install quickly with one easy step. You must have a Dedicated Server, VPS or Cloud Plan with cPanel to use Softaculous.
If you were using Fantastico to install your scripts we highly recommend you import them to softaculous, this is done just going to your Softaculous area in your cpanel and using the Synchronize link in the top/right menu.
We recommend you make a backup of your installation before proceeding just in case something go wrong, however that is very unlikely. Keep in mind you can also restore a backup using R1Soft Restore Backup option in your cPanel as well.
Note: R1Soft backups are not guaranteed, and are meant for your convenience only. Firewall issues, a hardware failure on a backup server, network problems or similar could potentially interfere with the backup system communicating with the individual servers. It's recommended that you make a periodic manual backup for safeguarding purposes.
