Experience Analytics exception after upgrade to Sitecore 8.2 from 8.1 update 2

Question

I have installed a fresh Sitecore 8.2 and deployed the solution built on 8.1 u2 on top of it.

I have updated all dll references beforehand to point to Sitecore NuGet for 8.2 version and updated web.config in the source control.

The site starts ok but i don't find any analytics data. I can see the visits in Experience Profile, but analytics dashboard is blank.

I am running SOLR as a content search provider.

I can see lots of exceptions like this in the log:

9552 16:45:13 ERROR Aggregation Error

Actually I tried dis-assembling that dll and that type exists.

Answer 1

EXM 3.3 does not run on Sitecore 8.2, so it makes sense that it's causing aggregation problems.

EXM 3.3 only runs on Sitecore 8.1 update 3 (rev. 160519).

EXM 3.4 runs on Sitecore 8.2 (rev. 160729).

You are always able to see which Sitecore version is required by a specific version of EXM on the Email Experience Manager download page

Answer 2

I have figured out that is related to EXM aggregation. so there is EXM 3.3.0 If i disable these configs:

Website\App_Config\Include\EmailExperience\Sitecore.EmailExp‌​erience.ExperienceAn‌​alytics.Aggregation.‌​config

Website\App_Config\Include\EmailExperience\Sitecore.EmailExp‌​erience.ExperienceAn‌​alytics.Reduce.confi‌​g

I see no exceptions.. Something is wrong around EXM... I also tried to install clean sitecore 8.2 and EXM on it - same error so nothing related to my code.
