Hi,

I need a help in deciding the migration plan for Azure AD connect. Currently, the Azure AD connect(1.6.14.2) server is running on Server 2012 R2 & SQL 2012 to host the databases. We need to move both the Azure AD connect and Database to the new servers and new machines are ready. I read several articles to use Swing method to perform this migration, but there are no steps to talk about database migration along with AD connect app. We need to host the new AAD connect database into new SQL 219 server. Can one of you please provide the possible steps to complete this migration successfully? Thank you so much.

Azure Database Migration service
Windows for business | Windows Server | Devices and deployment | Set up, install, or upgrade
Microsoft Security | Microsoft Entra | Microsoft Entra ID

    Hello @kannan

    The best practice of high level steps are:

    1.Export the existing AAD Connect configuration from the current server.
    2.Install the latest version of AADC on a new or existing Windows Server 2016 computer.
    3.Import the AADC configuration, put it into staging mode, and sync.
    4.Uninstall AADC from the old server.
    5.Remove the new server from staging mode.

    As reference for Import/Export operations I can recommend this official Microsoft article:
    https://learn.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-import-export-config

    In regards to the SQL Database, there is a more detailed guide here: https://learn.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-install-move-db

    Hope this helps with your query,

    @kannan , Thanks for reaching out.

    You can back up the ADSync database and restore it to new SQL server. After which (in step#2), you can install a new Azure AD Connect server and point it to the restored ADSync database using .\AzureADConnect.exe /useexistingdatabase.

    For detailed information, refer: https://learn.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-install-existing-database
