What method are you using? Have you looked through the API documentation?

This is being done with a query of a custom view:

// Add the main menu
DataQuery query = new DataQuery()
.From( "View_Custom_OLY_MenuItem" )
.Where( "Type", QueryOperator.Equals, "MainMenu" )
.OrderBy( "NodeOrder" );

viewModel.MainMenuItems = new InfoDataSet<TreeNode>( query.Execute() );

Let me ask another question that may help diagnose the problem ...

Is it possible that the GUIDs for DocumentNodes or any other node could change in a DB upgrade from 8.1 to 8.2?

you may try to add .OnSite("YourCodeSiteName") or .OnCurrentSite() to your query

 // Add the main menu
DataQuery query = new DataQuery()
.From( "View_Custom_OLY_MenuItem" )
.OnCurrentSite()
.Where( "Type", QueryOperator.Equals, "MainMenu" )
.OrderBy( "NodeOrder" );

Peter,

Unfortunately, DataQuery does not support those extensions.

I am thinking that this isn't related to sites at all and that just happens to be the error that surfaces.
