There are two fentanyl type patch delivery systems.
1) fluid filled reservoir --Duragesic and Sandoz generic
2) Mylan-- matrix type
Here is a PDF explaining the differences:

This PDF gives another version of a conversion chart (which should be considered an estimate only)
The fluid filled reservoir is prone to more accidents and diversion, because the drug is more easily extracted from it.
So Mylan has come up with the matrix form, to help prevent this.

Sandoz is also a reservoir type. Sandoz (Alza) in fact makes the patches for Duragesic (Jannsen) So if you cannot use the Mylan effectively, the generic form by Sandoz should be the same as Duragesic brand.
Patches in general are very complex ways to deliver drugs into the body.
They are still very new compared to other routes of administration. And hence they can have problems.
