Replacement of TCollection classes by NCollection templates

I am migrating from OCC 6.9 to 7.6. In the 7.0.0 Release note I have seen that TCollection classes have been replaced by NCollection templates.
Unfortunately the Upgrade Guide link does not work:

Can anyone tells me how to replace TCollection_BasicMapIterator, TCollection_BasicMap and TCollection_MapNode.
Thanks a lot.

You are referring to classes implementing internal details of legacy collections. It might be helpful to see exact definitions of your collections to give upgrading hints.

As for update guide, it could be found here:

Thanks for your response.
For example I have an heritage like;
class BRepMesh_DataMapIteratorOfDataMapOfIntegerPnt : public TCollection_BasicMapIterator
