Trending @Wipro; Can anybody tell the difference for FSC-CIS, WEF-CRS, DOP Alight, WEF- Engineering Edge ! Can we switch between any of them?

Hi Wiproites, I wanted to know the concept of these business units DU. Like if I am in enterprise applications and I am not able to get any project under Enterprise applications, so can I grab a project under other DU/SL mentioned above or is there any policy applicable for getting project in other DU? As I'm on LOP so wanted to know regarding it..
