Planning an upgrade from 9.1 to 10.1 m40 with update to Creo / SolidWorks 2013

Hay WC people,

We have a planned upgrade from Windchill 9.1 m60 to 10.1 m40.

We have some CAD users on Windows XP with a majority on Windows 7 using SolidWorks 2009 and Pro-engineer Wildfire 4.1

Along with the 10.1 upgrade we would like to move to Creo 2.0 and SolidWorks 2013.

Anyone had good/bad experiance with SolidWorks 2013 and WC 10.1?
