Upgrade Umbraco version from 4.7.1 to 6.0.1

To upgrade from a old version to new version is pretty straight forward. I have upgraded one my projects where I followed the steps below -

1. Download the Umbraco 6.0.1
2. Take a backup of your current site and the database
3. Copy the following folder and files from the downloaded new version 6.0.1 and paste into the old version

• /App-Plugins
• /bin
• /install
• /Umbraco
• /Umbraco-Client
• /Config
• /Views
• /Global.asax
• /web.config

     4.  Before copying web.config make sure all of your settings are transferred to the new web.config file
          e.g. appsettings
     5.  If you add anything in the ValidElements section in the tinyMceConfig.config file, make sure you  
          transfer your settings to the new file after copying. (the file is located under config folder) 
     6.  Also update the 404 settings in the /Config/UmbracoSettings.config file
          (<error404>1526</error404>)
     7.  Update the default email in the /Config/UmbracoSettings.config file
          (<email>your@email.here</email>)
     8.  Update /Umbraco/Config/Create/UI.xml (use winmerge tool to compare the old and the new files)
     9.  Update /Umbraco/Config/lang/en.xml (use winmerge tool to compare the old and the new files)
    10. Update /Config/xsltExtensions.config (use winmerge tool to compare the old and the new files)
    11. Delete the files below

• /bin/App_browser.dll
• /bin/App_global.asax.dll
• /config/formhandlers.config 

    12. Run the site and you should see the orange screen for setup. Provide the existing database details and
          click Next to complete setup. This setup procedure will automatically update the database for the 
          new version.

Hope this helps! Thanks.
