Dani Ljepava explains a new benefit:
Hybrid failover rights is a new benefit that allows you to run a license-free Azure SQL Managed Instance when used as a passive DR replica for your SQL Server 2022 licensed under Software Assurance (SA), or using Pay-as-you-go billing option.
How the Hybrid Failover Rights benefit works
The new Hybrid failover rights licensing benefit is technology agnostic. You can use any technology, such is MI link as the most advanced replication technology using Always On, or perhaps LRS, ADF, transactional replication, backup and restore, or similar to setup replication between SQL Server and Managed Instance. As long as you are using Azure SQL Managed Instance only as a passive replica for your SQL Server 2022, you are eligible to apply the new licensing benefit.
Read on for more details on how you can activate this benefit.
