upgrading Search service application database from SharePoint 2010 to SharePoint 2013

Hi, 

I am trying to upgrade SharePoint 2010 farm to SharePoint 2013 . I don't know how to migrate Search Service Application database from Sp2010 to SP2013. I did some Google and found nothing related with movingSearch service database ( http://technet.microsoft.com/en-us/library/jj729805.aspx ).

Is there any other way to upgrade Search Service Application Database ?
