Restoring a SQL Managed Instance database backup to SQL Server 2022 now GA

Restoring a backup file is the easiest way to copy a database to another instance. We are excited to announce that you can now restore a copy-only full backup of an Azure SQL Managed Instance (SQL MI) database to an instance of SQL Server 2022 hosted anywhere.
