We are building CRM 2013 & 2015 environments so that we can take our CRM 2011 instances through to current versions. We are aiming for 2 x CRM servers and 2 x SQL nodes in an alwayson configuration. The SQL nodes have 3 instances,
instance1 = CRM 2011
instance2 = CRM 2013
instance3 = CRM 2015
We have a Alwayson configuration working with CRM 2011 & instance1. We are now trying to get build the CRM 2013 deployment but are hitting various problems.
Document = https://technet.microsoft.com/en-us/library/jj822357(v=crm.6).aspx
We have;
Step1: Created SQL alwayson instance2 listener on custom TCP port
Step2: Installed CRM 2013 to named instance on SQL node1 then applied SP1
Step3: run through configuration to get CRM to connect to Alwayson using TechNet document. To get the Deployment Manager to open we had to add the port number to the registry key so we have... Data Source=SQLINS02AG,64800;Initial Catalog=MSCRM_CONFIG;Integrated
Security=SSPI
Step4: Installed the CRM2013 SRS reporting connector on SQL node 1 (having uninstalled the 2011 version), we had to use the local instance name and not the Alwayson listener
The problems we have are
1. When you try to create a new CRM organisation you have to change the values in the wizard back to one SQL node and NOT the Alwayson listener. Then the wizard errors:

2. We can't get the CRM2013 reporting extensions on the second node, we get the following error. "Microsoft Dynamics CRM Reporting Extensions is not compatible with this version of Microsoft Dynamics CRM. Upgrade Microsoft Dynamics CRM, and then try
again."
3. We can't get the second CRM server to install and connect to an existing deployment. " 09:42:57| Error| Check ConfigDatabaseVersionValidator : Failure: The specified database has a later version."
Any ideas would be greatly appreciated
