Hello,

I'm trying to upgrade my Umbraco website. Now the version of Umbraco is 6.1.6. 

I did the following to upgrade: 

  - copy these folders to website map: bin, install, umbraco & umbraco_client

  - merged /config folder, /global.asax, web.config (root & views) 

When I do the update wizard, I get this database error:

Upgrading Umbraco

The Umbraco database is being configured. This process upgrades your Umbraco database.

The database configuration failed with the following message: Invalid column name 'masterContentType'. Invalid column name 'masterContentType'. Invalid column name 'masterContentType'. Please check log file for additional information (can be found in '/App_Data/Logs/UmbracoTraceLog.txt')

Can someone help me with this, I can't find the sollution? 

Thanks in advance!
