SSRS 2016 Inplace Upgrade - ReportManager folder missing

Hi all

After installing SSRS 2016 (Version 13.0.4001.0)  as an inplace upgrade "over" an existing SSRS 2012 + Service Pack 3, I notice the \ReportManager folder no longer exists.

All I have in MSRS13.MSSQLSERVER\Reporting Services\

\LogFiles

\ReportServer

\RSTempFiles

\RSWebApp

sql_rs_keyfile.dll

ThirdPartyNotices.txt

Can anyone else confirm if this folder is no longer present / relevant in 2016 version?  The reason I ask is that previously we had to add lines to web.config file in..

MSRS11.MSSQLSERVER\Reporting Services\ReportManager\web.config

Such as: 

  <appSettings>

..

<add key="aspnet:MaxHttpCollectionKeys" value="10000" />

.. 

</appSettings>

And also tweak the ReportingServices.js file in

MSRS11.MSSQLSERVER\Reporting Services\ReportManager\JS

There is nothing clear I could find on the MS site to confirm if this folder / web.config is still relevant

Any help much appreciated

Thanks

Andy
