Can we use Tata Indicom broadband connection on Tata Docomo broadband connection wire

Can we use Tata Indicom broadband connection on Tata Docomo broadband connection wire.
I have two active connections
1. Tata Indicom Broadband tataindicombroadband.in
2. Tata Docomo braodbandtatadocomo.com/

Both are wired broadband connections. And for both connections I have separate modems.
As we knows all tata internet companies are merged into Tata Docomo. Tata Indicom broaband internet trafic is routed through Tata docomo servers.
Recently I shifted to another flat in same city Pune. There is no connectivity for Tata Indicom. So I got Tata Docomo connection. Now my question is can I use my old Tata Indicom braodband connection login username and password using new Tata Docomo wire (as I have two separate modems for each connection). If yes then will anybody please tell me how to configure Tata Indicom connection.
Any help will be greatly appreciated.

Why don't you simply try and see if that works. let us know what you get when you try it over other connection.
