- Dolphin ... many more!
If you were using Fantastico to install your scripts, we highly recommend you import them to Softaculous. This is done just by going to your Softaculous area in your cPanel and using the Synchronize link in the top right-hand side menu.
We recommend you back up your installation before proceeding just in case something goes wrong. However, that is very unlikely. (Keep in mind you can also restore a backup using the R1Soft Restore Backups option in your cPanel as well).
