    No factory has been set error after Upgrading Umbraco 7 to Umbraco 8

    Hello,

    I'm in the process of trying to do a quick Umbraco 7.15.4 to Umbraco 8.15.0 upgrade and I'm getting an error when running via Visual Studio after I've upgraded all of the packages and fixed references.

    I've tried the suggestions mentioned below:

    Global.asax contents:

    <%@ Application Inherits="Umbraco.Web.UmbracoApplication" Language="C#" %>
    

    I'm wondering if maybe I have an error in my \App_Start\UmbracoEventsHandler.cs file after I migrated to the new format for components and composers? UmbracoEventsHandler.cs file:

    using System;
    using System.Web.Http;
    using System.Web.Optimization;
    using Umbraco.Core;
    using Umbraco.Core.Composing;
    
    
    namespace ProjectSite.App_Start
    {
        public class ApplicationComposer : ComponentComposer<ApplicationComponent>, IUserComposer
        {
            public override void Compose(Composition composition)
            {
                // ApplicationStarting event in V7: add IContentFinders, register custom services and more here
                GlobalConfiguration.Configure(WebApiConfig.Register);
    
                composition.Components().Append<ApplicationComponent>();
    
                base.Compose(composition);
            }
        }
    
        public class ApplicationComponent : IComponent
        {
            public void Initialize()
            {
                // ApplicationStarted event in V7: add your events here
                BundleConfig.RegisterBundles(BundleTable.Bundles);
                GlobalConfiguration.Configuration.Formatters.JsonFormatter.MediaTypeMappings.Add(new System.Net.Http.Formatting.RequestHeaderMapping("Accept",
                                  "text/html",
                                  StringComparison.InvariantCultureIgnoreCase,
                                  true,
                                  "application/json"));
            }
    
            public void Terminate()
            { }
        }
    }

    Any help would be much appreciated! Thank you! Chris

    Hi Chris

    Generally the advice is that there isn't a direct upgrade path from V7 to V8 - but there is a migration path, where you get to keep your content.

    https://our.umbraco.com/Documentation/Fundamentals/Setup/Upgrading/migrating-to-v8?_ga=2.152323001.1664531814.1564385463-1412256652.1558683561

    Essentially, Start with a new Visual Studio project, install V8, and point it at the database to update the database structures and migrate the content. Then reimplement your site, in the V8 solution, start by moving in your views, etc, and updating all the syntax - rewrite any application starting hookins etc to use Composition and Components.... etc etc

    It will be really hard to get a V7 solution to run if you just Nuget it to V8, and you need it to run to able to upgrade the database!

    regards

    Marc
