How do i get info from Bitcoin QT 0.7 to Bitcoin QT 0.11? I'm having trouble with Bitcoin QT 0.11 not automatically extracting address info from my Bitcoin QT 0.7. When I try to open my Bitcoin QT wallet it comes up with an error code saying it is to unsafe to continue. How can I get hold of my info from my Bitcoin QT wallet.
A blkindex.dat error means that the block index has been corrupted or can't be opened. However, the block index is not part of the wallet, and can be deleted without removing the funds in your wallet.

With that in mind, try this:


Open %APPDATA% in file explorer. Do this by pressing Windows + R, then typing %APPDATA%.
Open Roaming\Bitcoin.
Make a new folder in there called 'old block files,' or something similar.
Move every file in that folder except wallet.dat into the old block files folder.
Optionally, delete the 'old block files' folder.
Start Bitcoin 0.11, and your computer will redownload the block chain. This will take a few hours.
