Restoring an SQL Server database to an alternative instance
By using Microsoft Management Console (MMC), you can restore an SQL Server database backup to an alternate SQL Server instance or database. You can also restore availability databases to an alternative location on any availability replica in an availability group. You can restore to an alternate instance by using Microsoft Management Console (MMC), Windows PowerShell cmdlets, or the command-line interface (CLI).

Alternate Location. The Restore VerifyOnly to Alternate Location task is available only if all the selected database backups are legacy backups.Important:
When you select the Restore VerifyOnly to Alternate Location action, the stripes number must be the same or greater than that which is set in the backup. If it is not, the Restore VerifyOnly operation terminates with an error.
For a legacy backups, select the SQL Server instance which you want to restore to. In the
Restore Into section of the Alternate Location Restore
Settings window, click Restore to new database, and specify a
target SQL Server instance name and target database name to restore a backup object to.
The Database name can have the same name as the source database or you can specify a different unique name.

- In the Relocate section of the window,
filter the restore processing operations.

Select a folder or create a new folder, and click OK. The path of the selected files entries is set to use the folder. This option is available for legacy backups only.Tip: When you restore a VSS backup to an alternate SQL Server instance, the Restore to original location processing option is disabled, However, it is still possible to restore to the original location by entering the same database name and database file path as in the original location.Restriction: You cannot relocate database files and logs with a partial restore operation in MMC. You must use the command-line interface to complete a partial restore operation that requires these parameters.
