Based branch in tcs

I have completed 2.8 years in TCS at that time. My base branch is in Bhubaneswar I have asked my manager to change my base branch he told me to raise a self-initiated transfer. It's approved and now my deputed branch is in Mumbai. Now I have been released from the project do I have to visit Mumbai as my Deputed branch or Bhubaneswar as it is my based branch?
