    Hi Praveen,

    In my experience the best upgrade path from 4.0.x is to 4.5.2, and then 4.7.0, followed by 4.7.1 (recommended if you want to start using razor).

    Here's a link to a small guide I've written and updated for several upgrades:

    Upgrading from 4.8 to 4.9 Umbraco.  I have followed the steps above, but got the installation wizard rather than the upgrade wizard. 

     

    Am currently getting this error:

     

    - EventData

      HRESULT 0x800700b7

      PhysicalPath \\?\E:\websites\www.min-ns.net\httpdocs\httpdocs\web.config

    Type 3

      Message Cannot add duplicate collection entry of type 'add' with unique key attribute 'key' set to 'umbracoDbDSN' 

      LineNumber 28

      PreviousLine <add key="umbracoDbDSN" value="server=srv-portal1;database=minnpocumbraco;user id=adminrl;password=MIN-NS5-15-12" /> 

      ErrorLine <add key="umbracoDbDSN" value="" /> 

      NextLine <add key="umbracoConfigurationStatus" value="" /> 

     

    Any help would be appreciated,

    Maryann

    Hi,

    According to the error your web.config has two duplicate appSettings - you should delete the second one listed under ErrorLine (<add key="umbracoDbDSN" value="" /> )
