replacing the blockchain

[Renth]

The blockchain is located under the "blocks" folder (~/.bitcoin/blocks)
starting from the version 0.8 and above of the bitcoin client.

So I copied the blocks folder into another (~/bitcoin-test),
started the client - ~./bitcoin-qt -datadir=/home/username/bitcoin-test
but the wallet does not open, it just loads eternally in the tray.

Please help and clarify how to properly replace the blockchain,
Thanks

You should copy the entire ~/.bitcoin/ to ~bitcoin-test/
cp -Ri ~/.bitcoin/ ~bitcoin-test/
then I am sure ~/.bitcoin-qt -datadir=~/bitcoin-test should work.
