New Post: Checking C1 4.0 IUSER Table Structures Same as 3.2 ?

Hi,
I'm looking at V4 and noticed when using the SQLdataprovider conversion tool for an empty after creating a few data sets before the conversion. Resulted in a list of schema warnings afterwards:

Message 1   Could not find schema information for the element 'Composite.Data.Plugins.SqlDataProviderConfiguration'.    D:\\CODE WORK\_C1 V4\Website\App_Data\Composite\Configuration\DynamicSqlDataProvider.config 6   6   D:\...\Website\

I just wanted to check if there has been any datatable structure changes regarding any of the IUSER tables in C1 since V3.2?
