Upgrade from CRM 2011 to CRM 2013

Hello Experts,

We were trying to upgrade from CRM 2011 (5.0.9690.4376) to CRM 2013 (6.1.4.145).

Below is the set up that we got in Production when we did the CRM 2013 upgrade.

Type	Role (2011)	OS (2011)	Role (2013)	OS (2013)
Web	Full server	(Windows 2008 R2)	Front End Server, Deployment Manager	(Windows 2012 R2 Standard)
Web	Full Server	(Windows 2008 R2)	Front End Server, Deployment Manager	(Windows 2012 R2 Standard)
Web	Front End Server, Deployment Manager	(Windows 2008 R2)	Front End Server, Deployment Manager	(Windows 2012 R2 Standard)
App	Full Server	(Windows 2008 R2)	Full Server	(Windows 2012 R2 Standard)
App	Full Server	(Windows 2008 R2)	Full Server	(Windows 2012 R2 Standard)
App	Full Server	(Windows 2008 R2)	Full Server	(Windows 2012 R2 Standard)
SQL	SQL Server 2008 R2	(Windows 2008 R2)	SQL Server 2008 R2	(Windows 2008 R2)
SRS	SRS Data Connector	(Windows 2008 R2)	SRS Data Connector	(Windows 2008 R2)

We got 3 service accounts; none of these are added to CRM as user;

ServiceAccount1 – Asynchronous Service, Deployment Service, Monitoring Service, Unzip

ServiceAccount2– Sandbox

ServiceAccount3– VSS

ServiceAccount1 - CRMAppPool and DeploymentServiceApppool

Loadbalancer– Connected to the 3 web servers above

With above setup we were able to complete the upgrade without any issue, we were able to access CRM organization from browser, and we were able access all the CRM services from browser.

But, we have CCA framework as front-end which consumes CRM services to open the session for customer.

CCA framework calls out CRM organization service to retrieve details from CRM.http://hostname:5555/VirginMedia/XRMServices/2011/Organization.svc

But when agents tried to launch our client, it throws error stating organization service sent back a fault indicating it is too busy to process the request. Please retry later, please see the inner exception for fault details. There are too many active security negotiations or secure conversations at the service.

CallBacksRetrieve System.ServiceModel.ServerTooBusyException: Server 'hostname/.../Organization.svc' sent back a fault indicating it is too busy to process the request. Please retry later. Please see the inner exception for fault details. ---> System.ServiceModel.FaultException: There are too many active security negotiations or secure conversations at the service.

Please help.
