Manage different versions of WSUSoffline

Hi,
Once I used wsusoffline_8.9 to download WIN7 updates, probably the updates are stored in CLIENT folder. Now I have wsusoffline_10.4. Do I need to move CLIENT (8.9) to CLIENT (10.4) so that UpdateGenerator.exe don't download the previous updates once again? Is there any other folder (other than client) need to copied under 10.4?
Thanks in advance.
