Microsoft Dynamics CRM Server upgrade preparations
Applies To: CRM 2015 on-prem
To prepare the upgrade, follow the guidelines in this section.
Microsoft Dynamics CRM Server 2013 roles aren’t compatible with a Microsoft Dynamics CRM 2015 deployment. Therefore, after you upgrade the first Microsoft Dynamics CRM Server, other Microsoft Dynamics CRM 2013 servers that are running in the deployment will become disabled. As each server is upgraded, it will be enabled.
|We recommend that for each organization that you upgrade, the volume have free space that is at least three times the size of the organization database file and four times the size of the log file. Therefore, if a single organization database and log file are located on the same volume and are one gigabyte in total, you should have at least seven gigabytes of available disk space before you perform the upgrade.|
This section provides best practices for managing Microsoft Dynamics CRM deployment downtime that will be incurred during an upgrade.
Upgrade in a test environment to estimate the duration of downtime and determine issues that may occur as a result of the upgrade. More information: Upgrade the Microsoft Dynamics CRM Deployment
Consider a phased approach to upgrade.
Microsoft Dynamics CRM Server upgrade only (binary upgrade). To do this, don’t specify an organization during the upgrade.
Important After the Microsoft Dynamics CRM Server upgrade is complete, all Microsoft Dynamics CRM 2013 organizations are disabled and can’t be enabled until they are upgraded.
Upgrade organizations. Use the Import-CrmOrganization Windows PowerShell command to upgrade each organization. More information: Administer the deployment using Windows PowerShell
Alternatively, you can use Deployment Manager to individually upgrade each organization.
- Microsoft Dynamics CRM Server upgrade only (binary upgrade). To do this, don’t specify an organization during the upgrade.
Before you run the upgrade, we recommend that you install or enable the following components on the computer where you will install Microsoft Dynamics CRM Server or on the computer where Microsoft Dynamics CRM Server will be migrated to:
Windows Identity Foundation Framework (must be enabled using Server Manager or Windows PowerShell add-windowsfeature command)
.NET Framework 4.5.2
Microsoft SQL Server Native Client
Microsoft Application Error Reporting Tool
Microsoft URL Rewrite Module for IIS
If these components aren’t present when you run the upgrade, Setup will install them. However, to reduce the upgrade processing time, consider installing these components in advance. If you install from a DVD, these components can be found in the redist folder of the Microsoft Dynamics CRM installation media.
