DRAG DROP
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.
You need to upgrade all content databases and minimize monitoring requirements.
What should you do? (To answer, drag the appropriate terms to the correct location or locations in
the answer area. Each term may be used once, more than once, or not at all. You may need to drag
the split bar between panes or scroll to view content.)
Explanation:
Note:
* To attach a content database to a web application by using Windows PowerShell
Start the SharePoint 2013 Management Shell.
At the Windows PowerShell command prompt, type the following command and then press ENTER:
Mount-SPContentDatabase -Name DatabaseName -DatabaseServerServerName -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.
