Trending @Infosys; Request for Guidance Regarding Transfer Letter

Today, I received a transfer letter stating that I have been moved from DX to HTAMD. I am not familiar with what HTAMD team or what this transfer involves. I currently do not have any knowledge about this new department/team and would really appreciate it if someone could guide me on the next steps, responsibilities, and expectations and why they transferred me. Thank you in advance for your support.
