We are plannning to upgrade from Tridion 2011 SP1 to Tridion 2013 SP1. In our implementation we are using TOM.Net for Templates and event system. Core services for custom pages and a simple GUI extn. According to deprecation guide, I couldn't see which all methods are getting deprecated in TOM.NET used for templates and event system code and core service methods as well. I need this to decide and plan migration strategy. Help me with any documentation which lists all the methods which are getting deprecated in TOM.Net,Core service API, GUI extn.
