COMSOL compatibility version 4.0 vs. 4.3

I have been using COMSOL 4.0 until recently (I know it's pretty old but I had no complaint with 4.0) for a microfluidic fuel cell application.
Two weeks ago, the license finally expired and I had to install a new 4.3 in my computer. So I ran an old case that was originally created by 4.0 version to see if there is any issues. The convergence was fine and it looked totally OK until I investigated the results: the currents produced were far off from what I typically got using 4.0. I double checked everything in my setup and could not find anything wrong. Basically, I didn't change any settings/parameters but simply ran the old case files in the new version. Here is a list of modules used in my model:
-. Secondary Current Distribution
-. Free and Porous Media Flow
-. Transport of Diluted Species
Has anyone experienced this weird behavior between different versions of COMSOL? Does anyone know how to resolve this issue?
Your comments will be greatly appreciated.
thanks in advance,
