relocating already downloaded packs (UpdateInstaller)

I have already downloaded the required update packs for [wxp]. I did not check the [Copy updates for selected products into directory]. Now if I want to relocate them to another folder to be used together with UpdateInstaller.exe can I just copy the [client] folder anywhere I like? Will it work? If not is there a way to relocate already downloaded stuff or do I have to download everything again with that option turned on? Thanks.
