Hi Mani,
Thanks a lot for the guidance and extraordinary help. Although when we tried to use "ContainerMoveHelper" class, it was not found by the program. I checked and found that in 10.1, it's not there anymore. I'm trying to find out the replacement class which they have in Windchill 10.1.
Do you know which class to use instead?
Again, I really appreaciate your help on this. I owe you big 
Thanks,
Wasim
