Mumbai Shops & Establishment License for addition of new premises?

We are Pvt ltd Company & have Office cum workshop in Mumbai & have registered under Maharashtra Shops & Establishment Act. Also we have taken Trade License for doing Computer Repairing Activity.
Now we have taken one more premises in same building and shifted Workshop & Repairing activity to new premises.
Please advise whether we have to take new Shops & Establishment Registration of New Premises or we can do addition of new premises in existing Registration.
Also our trade Licenses can be shifted to new premises or new Trade Licenses have to be taken.

New premises at different location building will need new Shops Act registration (not license as you have mentioned).
You have mentioned activity of workshop. It may fall under factories act. Check with the shops act & factories act to be legally correct.
