How do I migrate Azure AD Connect to new server

Migrate Azure AD Connect to new server is a crucial task for organizations seeking to ensure uninterrupted identity synchronization between on-premises directories and Azure AD. In this comprehensive guide, we’ll walk through the process of migrating Azure AD Connect to a new server, including preparation, migration steps, and post-migration tasks. Additionally, we’ll address common FAQs and provide external resources to assist you throughout the migration process.

Understanding Azure AD Connect Migration

Azure AD Connect is a vital component for organizations utilizing Azure AD, facilitating the synchronization of on-premises directories with Azure AD. When migrating Azure AD Connect to a new server, it’s essential to ensure a seamless transition to maintain identity synchronization and minimize downtime.

Preparation for Migration

Before migrating Azure AD Connect to a new server, thorough preparation is key. Follow these steps to prepare for the migration:

  1. Review Current Configuration: Document the existing Azure AD Connect configuration, including synchronization settings, filtering rules, and any customizations.
  2. Verify Server Requirements: Ensure that the new server meets the system requirements for Azure AD Connect, including supported operating systems, memory, and disk space.
  3. Backup Configuration: Take a backup of the existing Azure AD Connect configuration using the built-in configuration backup feature. This backup will serve as a safeguard in case of any issues during the migration process.
  4. Communication Plan: Notify stakeholders about the upcoming migration to minimize disruption and ensure awareness of any potential impact on identity synchronization.

Migration Steps

Once you’ve completed the preparation phase, follow these steps to migrate Azure AD Connect to a new server:

  1. Install Azure AD Connect on the New Server: Download and install Azure AD Connect on the new server following the same steps as the initial installation. Choose the option to customize settings during installation to match the configuration of the existing server.
  2. Configure Azure AD Connect: During the installation process, select the option to use an existing Azure AD Connect configuration. Provide the necessary credentials to connect to Azure AD and select the appropriate settings to match the existing configuration.
  3. Synchronize Directories: Once Azure AD Connect is installed and configured on the new server, initiate a full synchronization to ensure that user identities and attributes are synchronized between on-premises directories and Azure AD.
  4. Verify Synchronization: Monitor the synchronization process to ensure that all user accounts, groups, and attributes are replicated successfully to Azure AD. Use tools such as the Azure AD Connect Health dashboard to monitor synchronization status and troubleshoot any issues.
  5. Switch DNS Records (Optional): If you’re using custom domain names for Azure AD authentication, update DNS records to point to the new server to redirect traffic from the old server to the new one.
  6. ** Decommission Old Server**: Once you’ve confirmed that Azure AD Connect is successfully migrated and operational on the new server, decommission the old server. Ensure that all necessary data and configurations are transferred before decommissioning the old server.

Post-Migration Tasks

After completing the migration process, perform the following post-migration tasks to finalize the transition:

  1. Verify Functionality: Test user authentication and access to ensure that identity synchronization is functioning as expected on the new server.
  2. Update Documentation: Update documentation and configuration records to reflect the new Azure AD Connect server configuration and any changes made during the migration process.
  3. Monitor Performance: Monitor the performance of the new Azure AD Connect server to ensure optimal operation and identify any potential issues or bottlenecks.
  4. Implement Disaster Recovery Plan: Establish a disaster recovery plan to mitigate the risk of data loss or service disruption in the event of a server failure or other unforeseen circumstances.
