Driving licence of any state is valid in any state of India. If you have original driving licence with you and if you can show it to somebody on demand, you can drive anywhere in India. As far as I know statewise driving licences are not required.
But if the vehicle belongs to other state and you want us to use continuously in another state or you are shifting to another state the vehicle registration should be changed. First they will give some time to use the vehicle without changing the registration. Within that time frame you have to change your vehicle registration.
But driving licence of Individual is valid all over India. You can drive anywhere. But other countries it is not valid. When you go to other countries if you have to drive vehicle there you have to take a licence there which is known as international driving licence.
