Undo.SetSnapshotTarget is obsolete: Use Undo.RecordObject instead

Hello, still trying to learn Unity.
One of my assets is giving me a lot of obsolete alerts and i want to learn.

What i need to do with "CreateSnapshot" and "ClearSnapshotTarget" ?

Is correct to change this code ?

Code (csharp):

1.  
2.                         // Create a new snapshot.
3.                         Undo.SetSnapshotTarget (p_target, p_name);
4.                         Undo.CreateSnapshot ();
5.                         Undo.ClearSnapshotTarget ();
6.  

with this new code?

Code (csharp):

1.  
2.                         // Create a new snapshot. Unity 4.5
3.                         Undo.RecordObject (p_target, p_name);
4.                         // Obsolete: Undo.CreateSnapshot ();
5.                         // Obsolete: Undo.ClearSnapshotTarget ();
6.  

I don't know what i'm doing and i'm afraid to loos my prefabs setups or to loos functions:
CreateSnapshot and ClearSnapshotTarget.
Is there anybody good to learn from at this night time?
