TWO SSRS Reporting Extension on one node for CRM 2011 and CRM 2013

Hi All,

We have both CRM 2011 and CRM 2013 in our environment.

I need to install SSRS Reporting Extension for CRM 2011 and CRM 2013. SSRS and SQL is installed on same machine but we are using two different node of SQL server but box is one for 2011 and 2013.

My assumption is only one version of reporting extension can be installed on one machine?

Thanks

Hassan
