There are three different upgrade options:
Migrate by using a new instance of Microsoft SQL Server. We recommend this option for upgrading Microsoft Dynamics CRM Server. Although this option requires a different computer for Microsoft Dynamics CRM Server 2015 and a different instance of SQL Server, it provides the least amount of potential downtime for Microsoft Dynamics CRM because the previous Microsoft Dynamics CRM deployment can remain functioning until the upgrade is completed and verified.
Migrate by using the same instance of SQL Server. This option requires a different computer for Microsoft Dynamics CRM Server 2015, but will upgrade in-place the configuration and default organization databases using the same instance of SQL Server. If issues occur during the upgrade, you must roll back to the previous deployment to avoid significant downtime.
In-place upgrade. Although this option doesn’t require a different computer for Microsoft Dynamics CRM Server 2015 or a different instance of SQL Server, it poses the greatest risk if upgrade issues occur because a roll back and reinstall of the previous deployment will be required to avoid potential downtime.
|To upgrade, the deployment must have at least Microsoft Dynamics CRM 2013 Service Pack 1 (SP1). You can’t upgrade versions of Microsoft Dynamics CRM Server or Microsoft Dynamics CRM organization databases that are earlier than Microsoft Dynamics CRM 2013 Service Pack 1 (SP1). For information about how to migrate versions earlier than Microsoft Dynamics CRM 2013, see Upgrade from Microsoft Dynamics CRM Server 2011.|
