In order to have a success SharePoint 2013 upgrade as we discussed in design andarchitect of the prepare the existing SharePoint 2010 farm, the first and key step is the SharePoint 2010 farm inventory and reports.

You should always check the OoB new features and verify whether anything can customizations can be replaced. Please check depreciated features and prepare for replacement as we discussed before.
