    Upgrade Umbraco from version 6 to 7

    Hi guys,

    I'm trying to upgrade existing Umbraco site from version 6.1.5 to 7.2.2. I have upgarde the umbraco package using nuget package manager and solved all the build errors and config errors. Now i'm able to open up the Umbarco backoffce in version 7.

    But when I try to navigate to the document types, dictionary items, installed packages etc (all the components which is in settings and developer tab in Umbraco back office), it gives me following errors. when i try to access the document types it gives me error like image 1. And when i try to access other items in settings and developer tabs it gives me error like image 02.

    Image 01 error -

    System.NullReferenceException: Object reference not set to an instance of an object.

    Image 02 error -

    Method not found: 'Void umbraco.editorControls.ResourceExtensions.RegisterEmbeddedClientResource(System.Web.UI.Page, System.Type, System.String, umbraco.cms.businesslogic.datatype.ClientDependencyType)'.

    According my read, uComponents which used in Umbraco 6 was not compatible with Umbraco 7. I think this error is related to that.

    Can anyone help me reagdring this error please.

    What version of uComponents are you using? uComponents v6.1.0 should not break Umbraco v7:
