How to upgrade from DEBIAN SQUEEZE to DEBIAN WHEEZY

Hi friends!i am on my way to help DEBIAN.Here i am describing the process of upgrading from SQUEEZE to WHEEZY.First of all you   should have DEBIAN SQUEEZE running on your PC to do this upgrade.
You may have third party softwares   installed on your debian,better to remove them for a safe UPGRADE.update your /apt/sources.list   in the following way:
  • replace the word "squeeze" with the word "testing" or "wheezy" .
  • it is just enough to have your mirror(with replaced word as told in step.1)  to perform UPGRADE
  • i am pasting my sources.list here: 
  • ############################
    # Testing US mirror:
    deb http://ftp.us.debian.org/debian/ testing main contrib non-free
    #deb-src http://ftp.us.debian.org/debian/ testing main contrib non-free

    # Testing Security Updates
    deb http://security.debian.org/ testing/updates main contrib non-free

    #Testing Proposed Updates
    deb http://ftp.debian.org/debian/ testing-proposed-updates main contrib non-free


    ## Multimedia ##
    # Marillat For info visit http://www.debian-multimedia.org
    deb http://www.debian-multimedia.org testing main non-free
  • ############################
Then try to run   this command #apt-get update
If you have any  public key errors refer this:


  1. Then run this command  to simulate the upgrade   #apt-get -s dist-upgrade
  2. Next download all the packages for the upgrade:  
  3. #apt-get --download-only    dist-upgrade
  4. then finally reboot your PC and enter in to restore mode
  5. then perform dist UPGRADE using command #apt-get dist-upgrade
if you have any problems in the above please refer this 
or mail me.
