Query about BAU change

Hey Guys,

Currently I'm in NGM MEA BFSI BU. I'm a lateral entry in TCS, in May I'll complete 1 year(total I'll complete 4 yrs soon). Although I was hired as an Angular Developer, I'm getting interested in Cloud and AI domain. Recently TCS launched a new BU as Cloud AI.

How can I change from BFSI to Cloud AI? Any idea Guys?

Thanks in advance :)
