Moving address book between Evolutions

On my computer, I have Suse 10.1 and 11.1 partitions and am shifting information from the latter to the former. Getting the Evolution address book to the new version is proving a headache. With bookmarks and folders (inbox etc), I simply went into my document folder, clicked on hidden folders and simply dragged them onto an external hard drive. Whilst on 11.1, I simply dropped them on the existing folder and voila! But the address book doesn’t seem to work like that. Why not? In extremely simple terms, how can I move the address book across?
Many thanks.

This is crazy. After redropping the address book file over the one in 11.1 nothing initially happened. Now, the addresses are there! Is there a ghost in the machine? Also, in 10.1 there was an address book tab at the top and you could actually see the addresses in a list on the bottom left hand side of the screen. Have both these functions gone? I found the latter quite useful.
