With the main client,

with the old 0.7 client i copied only the blk*.dat files
then for restore i simply
created a new .bitcoin dir, i put inside the decompressed blk*.dat files and my wallet.dat
and then i started
bitcoin-qt -rescan

HOW TO DO THIS WITH THE NEW 08. CLIENT?
it seems saving the blk*.dat files is no more enough,
there are some new dir. Help.

Thank you in advance.
