Introduction
SP Transfer is able to transfer various items between two Joomla! databases. You install SP Transfer on the destination site, and you transfer items from the source database.
In no case an item will overwrite an existing item with the same id during transfer if you choose it. There is also a restriction in Joomla! where you cannot have the same alias of an item under the same parent. Taking these facts into consideration there are two important options you have to decide before the transfer.
