You are preparing to upgrade from a SharePoint 2010 environment to a SharePoint 2013 environment.The SharePoint 2010 environment includes a large number of content databases. You restore backups of the
content databases to the Microsoft SQL Server instance in the SharePoint 2013 environment.

Explanation:
Note:
* To attach a content database to a web application by using Windows PowerShell Start the SharePoint 2013Management Shell.
At the Windows PowerShell command prompt, type the following command and then press ENTER:
Mount-SPContentDatabase -Name DatabaseName -DatabaseServer ServerName – WebApplication URL
* Attach the remaining databases (no need to wait until first command finishes and use new instance)
After you restore the first content database and verify success, you can continue to restore and upgrade other
databases. You can perform parallel database attach upgrades to upgrade more than one database at a time.
Use separate Command Prompt windows (i.e new instance) to run multiple upgrades. It is recommended that
you separate the start time for each new database upgrade session by several minutes to prevent issues with
temporary locks set for the web application during attachment.
Otherwise you might receive an error on the upgrade session.
The wait time to clear temporary locks varies depending on the number of site collections, or the speed of the
database server hardware.
