importing all blkXXXXXX.dat I've moved my bitcoind process to a new server, I made a backup of my .bitcoin folder (I'm using linux). I would really like to avoid downloading the whole blockchain again.

What's the right way to import all the blk00000.dat files? Is it enough to move the .bitcoin folder over the new one?

EDIT: I see the Loadblock option but I suppose I should run it after move the file outside.Anyone can confirm this? Is there a better way?
Copy these files to a exact Bitcoin Data folder on your Ubuntu (~/.bitcoin/) and then run client to download the latest blocks available. To synchronize with the blockchain run bitcoind with command -reindex bitcoind -reindex.
