Make sure that you have removed or disabled the following dlls:

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

As per the recommendation from Sitecore:

xAnalytics assembly files

If you have implemented custom code that uses ASP.NET Web API attribute routing, to avoid errors we recommend that you disable the following .dll files in the \Website\bin folder:

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