Q. Does Fantastico allow auto upgrades to my existing joomla installation?
Ans. Fantastico stores installation data inside your account (below public_html). You will need to ensure that you make proper package of your account before uploading that on our servers. You can also get the account transfer done from our staff as we can get this done quickly and you won’t loose any data from your account we would take care of your data transfer.
Mostly Webmasters prefer to upgrade Joomla manually as upgrade from Fantastico overrides custom styles and navigation so you need to make sure that you take a full backup of your Joomla installation before upgrading from Fantastico.
