Hi!
The CopyWebAttributes function is documented in the Framework Reference section under the namespace EPiServer.Web.PropertyControls and the type PropertyDataControl.
Maybe you hit search and clicked on one of the results there, in that case you might have clicked the wrong version in the result-list and been directed to the obsolete method. If you use the Framework Reference TOC-tree you should find the correct one.

P.S Sorry about the late reply, seems I clicked Create New Topic instead of Reply last time. D.S
Sorry for waking up an old thread, but I cant really find how to use the CopyWebAttribute. The Framework Reference still points out CopyWebAttribute eventhough its absolete. Anyone that could be so kind to explain how to use this under epi5?
