Can we change the enhancement set for a component

Question

Dear All
I have a situation where in we need to change assign a different enhancement set to all our components which got enhanced.
We can only have 1 enhancement set active for a client.
Now in our case
Say for client 300 we were using Enhancement Set E1.
Our requirement is to create one more enhancment set E2 and assign it to client C1. We can do that.
Do we we have a mechanism to move all development already done using E1 to E2?
Please Help.
Thanks

Hi Gaurav,
               We create enhancement set in SM30, then assign it to client also there.
After that, when we go to BSP_WD_CMPWB - by default we see the enhancement set assigned to the client. Now there are 2 things:
1. to use different enhancement set for different users - you can implement badi component_loading to load different enhancement set depending on business requirement by writing code:
RV_RESULT = <name of ENHANCEMENT_SET. >
  there is a default implementation in the system for reference.
2. all enhanced views can be seen in transaction SM34, give name of view cluster as  BSPWDVC_CMP_EXT
   Select your enhancement set -> go to Enhancement Definitions (here you see components enhanced) -> select any -> go to Controller Subsitutes (here you see all view enhanced).
  You can try copying all these entries into another enhancement set. I am not sure if it will allow same entries in two different sets (if it doesn't you will have to delete from the other).
I hope that resolves your query.
Thanks,
Rohit
