Upgrade Multiple Deployments of Microsoft Dynamics CRM 3.0 That Share an Instance of SQL Server If you have multiple Microsoft Dynamics CRM 3.0 deployments running on a single instance of 
SQL Server and you plan to upgrade all deployments to Microsoft Dynamics CRM 4.0, you have 
three options available to complete the upgrade. Notice that you cannot install multiple Microsoft 
Dynamics CRM 4.0 deployments by using a single instance of SQL Server. This is because only 
one configuration database (MSCRM_Config) can exist on an instance of SQL Server.  
If you want to combine all Microsoft Dynamics CRM 3.0 deployments into a single deployment by 
using the Microsoft Dynamics CRM 4.0 multi-tenancy feature, you can use the Import 
Organization wizard that is located in the Organization node in the Microsoft Dynamics CRM 4.0 
Deployment Manager. Notice that only Microsoft Dynamics CRM 4.0 Enterprise supports multiple 
organizations in the deployment.  
If you upgrade the Microsoft Dynamics CRM 3.0 deployment and the SQL Server hosts multiple 
installations of the Microsoft Dynamics CRM 3.0 databases, you must select one of the following 
options to complete the upgrade. 
First, you must upgrade one of the Microsoft Dynamics CRM 3.0 environments by running 
Microsoft Dynamics CRM 4.0 Server Setup. This will create the configuration database and 
merge the Microsoft Dynamics CRM 3.0 databases into a single organization database. 
Next, you must upgrade the second Microsoft Dynamics CRM 3.0 environment. To do this, you 
must select one of the following options to complete the upgrade. 
Option 1: Restore the Microsoft Dynamics CRM 3.0
Databases to an Instance of SQL Server
To implement this option, follow these steps. 
1. Back up and restore the Microsoft Dynamics CRM 3.0 databases to another instance of SQL 
Server on the same computer or to another computer that is running SQL Server. For more 
information about how to back up and restore Microsoft Dynamics CRM 3.0, see the Microsoft 
CRM 3.0 Implementation Guide. 
2. Start Microsoft Dynamics CRM 3.0 Deployment Manager and associate the databases. For 
more information about how to do this, see the following Microsoft Knowledgebase article:
