How to change Tech Stack in Cognizant or How to prepare to switch to another tech with 3 years of Experience?

I’m in SAP Domain and want to switch my tech stack to something more stable like Development or DevOps. I’m fed up with night shifts and rotational shifts where i work my ass off continuously monitoring the systems and doing the same repetitive work every single day!!

Please give any suggestions if I can make a switch internally, and if yes.. how??!

If anyone has done it or any ideas to switch with 3 years of experience to a different company, it would be very helpful.
