Best approch to migrate SharePoint Site from 2010 to 2013.I want to migrate site develop in SharePoint 2010 to 2013. What is best approach ?
To upgrade from SharePoint 2010 Products to SharePoint 2013, you use the database-attach method to upgrade. In the database-attach method, you first create and configure a SharePoint 2013 farm. Then you copy the content and service application databases from the SharePoint 2010 Products farm, and then attach and upgrade the databases. This upgrades the data to the new version. Site owners can then upgrade individual site collections.

There are also third Party tools:
I would recommend an approach which increase chances of successful migration.
**Test Migration:**To understand your environment before you upgrade it, and to plan for the time that an upgrade will require, you should try one or more trial upgrades. The goal of testing upgrade is to find and fix issues and develop confidence in the outcome before the real upgrade.
Couple of points to be noted:
Final Migration: After complete testing, you have to perform the final migration.
I highlight the approaches, Anachal already mentioned how to migrate the 2010 to 2013 using the DB restore method. I always prefer DB upgrade unless you have 3rd party tool.
