Upgrade issue from 7.1 to 7.5 - add ons (Google Analytics )



I am facing issues when upgrading episerver project from version 7.1 to 7.5.

I have upgraded initially using the episerver deployment center and then through nuget packages, I updated the version to the latest version which is 7.19

I fixed all errors except there are few warnings but the project compiles successfully. When I run the project I got the following error related

to episerver google analytics. We have episerver google analytic add on installed on version 7.1. 

I have also run the "upgrade/disable Add-ons after product upgrade" but still the same issue as below:-

Does it ring a bell to anyone. Thanks in advance.

The error is :-

Server Error in '/' Application.

Hi Nazim,

It looks like you still have GA 7.1 binaries in your project? You'll need to update your GA add-on to versions compatible with 7.5 or else you may come across issues with your project.

Thanks Richly, I have tried adding Google Analytics through nuget package version as mentioned below:


EPiServer.GoogleAnalytics (only valid for version 8 and above) 
EPiServer.GoogleAnalytics (only valid for version 8 and above)

But still it did not work. I have seen a modeule and modulebin folder under root & modules folder under VPP. Can you confirm do I need to delete both or any of them?

By adding through nuget the 1.6 version, I can see a config file under module->protected. Is this correct?

You're still in base 7.5 (7.5.394.2) correct? Or have you updated to a more recent version of CMS 7.5? If you're still on base 7.5, then you're expected to see GA add-on folder under vpp/modules folder.  I think you may see some GA dlls in modulesbin folder as well.

Thanks for your reply. I have updated it to the 7.19 version and I have updated package from nuget too, but it is still the same. I can see dlls in my modulesbin folder? Do I need to remove them manually?

Yes, please try removing the assemblies in modulesbin.
