SQL failover cluster instance migration to cloud

We have requirement of migrating SQL failover cluster instance to Azure using lift and shift preferably (without much re-engineering or re-architecting)

  1. SQL cluster with 2 nodes. (OS - windows 2012 standard, SQL - 2012 sp4)
  2. Four SQL cluster instances(named) installed on it.
  3. SQL Instances SSIS, SSAS, SSRS of 2008 version

We are planning to move all roles to one node, demote the other node from cluster, shutdown the node and migrate node to azure.

Problem could be there are four sql failover cluster instances installed and how it will function same as existing once we migrate the SQL server to Azure.

    Hello there,

    The key factors to consider when you're evaluating migration options are:

    Number of servers and databases

    Size of databases

    Acceptable business downtime during the migration process

    Azure SQL Database is a recommended target option for SQL Server workloads that require a fully managed platform as a service (PaaS). SQL Database handles most database management functions. It also has built-in high availability, intelligent query processing, scalability, and performance capabilities to suit many application types

    Hope this resolves your Query !!

    Given the fact this architecture is already using AGs, you might want to take a look at the MI link in case your target is Azure SQL MI:


    Alternatively, depending on the target, you can consider DMSv2 to perform an online migration to Azure SQL. This type of migration leverages existing backups stored in Azure blob storage or a network share. The advantage of an online migration is that it will continuously restore any backups to the target while maintaining the source online. Then you can plan the cutover whenever you are ready to minimize downtime.

     Here you have the tutorials for MI and VM targets:
