4 tips for migrating to Sitecore 8.2

mei 16, 2017

I was recently given the challenge of migrating a Sitecore implementation from 6.5 to 8.2. I learned a few things along the way and I’d like to share them with you.

Tip #1: Try the Sitecore Express Migration Tool

Sitecore launched a migration tool that can help you migrate content. This tool is helpful – I would definitely recommend that you take a look at it.

Tip #2: Deal with the Global.asax on 8.2 issue

If you have any code running on "Global.asax" file, the method (Application_Start) will not fire on Sitecore 8.2.

Instead, you need to use some Sitecore pipelines to start that code.

In my particular situation, I had some MVC routes being defined on the Application_Start, so the solution was to implement an XML config patch to use a Sitecore pipeline to call the code.

In the sample below, I use the "Sitecore.Mvc.Pipelines.Loader.InitializeRoutes":


<configuration xmlns:patch="">




        <processor type="MyProject.Initialize.RegisterApiRoutes, MyProject " patch:before="processor[@type='Sitecore.Mvc.Pipelines.Loader.InitializeRoutes, Sitecore.Mvc']" />





Tip #3: Configuration changes for delivery servers

In order to properly configure a CD Server, you should be familiar with the Sitecore recommendations.

The major problem that I faced affected multiples pages. Here is the error message I saw:

{"Message":"An error has occurred.","ExceptionMessage":



at Sitecore.ExperienceAnalytics.Api.ApiContainer.CreateObject[T](String xpath)\r\n   at Sitecore.ExperienceAnalytics.Api.Http.Filters.NotFoundExceptionFilterAttribute..ctor()\r\n   at System.RuntimeTypeHandle.CreateCaInstance(RuntimeType type, IRuntimeMethodInfo ctor)\r\n   

at System.Reflection.CustomAttribute.GetCustomAttributes(RuntimeModule decoratedModule, Int32 decoratedMetadataToken, Int32 pcaCount, RuntimeType attributeFilterType, Boolean mustBeInheritable, IList derivedAttributes, Boolean isDecoratedTargetSecurityTransparent)\r\n   

at System.Reflection.CustomAttribute.GetCustomAttributes(RuntimeType type, RuntimeType caType, Boolean inherit)\r\n   at System.Web.Http.Controllers.HttpControllerDescriptor.InvokeAttributesOnControllerType(HttpControllerDescriptor controllerDescriptor, Type type)\r\n   

at System.Web.Http.Controllers.HttpControllerDescriptor..ctor(HttpConfiguration configuration, String controllerName, Type controllerType)\r\n   at Sitecore.Services.Infrastructure.Web.Http.Dispatcher.NamespaceHttpControllerSelector.InitializeControllerDictionary()\r\n   

at System.Lazy`1.CreateValue()\r\n   at System.Lazy`1.LazyInitValue()\r\n   at Sitecore.Services.Infrastructure.Web.Http.Dispatcher.NamespaceHttpControllerSelector.FindMatchingController(String namespaceName, String controllerName)\r\n   

at Sitecore.Services.Infrastructure.Web.Http.Dispatcher.NamespaceHttpControllerSelector.SelectController(HttpRequestMessage request)\r\n   at System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__1.MoveNext()"}

This error tells us that we missed one important step–some files must be disabled:

  • Sitecore.ExperienceAnalytics.dll
  • Sitecore.ExperienceAnalytics.Client.dll
  • Sitecore.ExperienceAnalytics.ReAggregation.dll

Tip #4: Framework Target

Don´t forget to update your Target Framework. If you forget to update it, you’ll experience multiple errors on your solution.
