Google Profile copying problems

Twice I have been bitten by something in the Dev channel breaking something I need, meaning I had to downgrade to the Release (stable) version. What I have discovered is that the Dev profile will not load in the stable release. After a long of trial and error, I have found that the following procedure makes this process somewhat painless.

  1. Go to the C:/Users/YourUserName/AppData/Local/Google/Chrome/User Data directory and copy the Default folder to Default-dev.
  2. Uninstall the Dev Channel version of Google Chrome.  It doesn’t matter if you tell it to delete your browsing history; you’ll be doing that later anyways.
  3. Download and install the stable release of Google Chrome.  When Chrome starts, shut it down.
  4. Delete everything in the C:/Users/YourUserName/AppData/Local/Google/Chrome/User Data/Default directory
  5. Copy the following files from the Default-dev directory to the newly-blank Default directory:
    2. Extensions
    3. History*
    4. Preferences
    5. Local Storage

Now when you open Chrome most of your settings should be there.
