We are upgrading from Tridion 2011 SP1 HR1 to Tridion 2013 SP1. So we are referring to the Tridion 2013 SP1 DLL to the solution in the Visual Studio. After adding the latest DLL build the solution which is giving the following warnings.
'Tridion.ContentManager.ContentManagement.OrganizationalItem.GetItems(Tridion.ContentManager.Filter)' is obsolete: 'Deprecated method. Use GetItems() or GetItems(OrganizationalItemItemsFilter) instead.'
'Tridion.ContentManager.ContentManagement.BinaryContent.FileSize' is obsolete: 'Use Size property instead. This property can't handle size more than 2GB.'
These warnings related to the deprecated still I'm worried whether these warnings will affect us or not? If yes, then how to resolve these warnings?
