Be sure you have at least the Minimum SharePoint 2010 Product Release (shown in the table below) installed before migrating. If not, upgrade your Bamboo product release before migrating. For more information, see Upgrading your Bamboo Web Part. Also, the target SharePoint 2013 farm requires at least the Minimum SharePoint 2013 product release shown.
IMPORTANT: When migrating from SharePoint 2010 to SharePoint 2013, the Database Attach Upgrade Method is the only method supported.
