You can create and maintain more than one organisation in Microsoft Dynamics CRM 4.0
Enterprise Edition. Upon installation, the user is asked for the details of the first organisation, but further to that, more organisations can be created through the Deployment Manager.
Alternatively you can add an organisation from another CRM installation by exporting and importing it into an existing CRM database, again through the Deployment Manager's Organisation tools. When performing an import, you need to take care to move the respective Active Directory (AD) information as well, by decoupling from the old AD information and recoupling with the AD information on the new installation. This is not a problem as the Import Organisation Wizard provides the ability to map all Active Directory Microsoft Dynamics CRM users from the source installation to valid Active Directory users in the new Microsoft Dynamics CRM installation. The Import Organisation Wizard will also update all primary and foreign keys to reflect the new environment and import all related reports.
You can choose to map users through either of 4 options:
1. Keep current users mapping
2. Manually map users
3. Generate new mapping file
4. Auto-map users based on the following parameters:
- Active Directory Account Name
- Microsoft Dynamics CRM Full Name to Active Directory Full Name
- Prefix and a start value
- An existing mapping file
Users can only access one organisation at a time, whether they are using the Web application or whether they are accessing Microsoft Dynamics CRM through Outlook.
