Log Replay Service (LRS) in preview for SQL Managed Instance utilizes log shipping technology to enable custom migrations of databases from SQL Servers 2008 through 2019 on-premises, or in a virtual machine, to SQL Managed Instance in the cloud. The LRS feature enables building fully customizable data migration solutions in cases when more control is needed, when there exists little tolerance for downtime, or when Azure Data Migration Service cannot be used.
