Migration Certificate

Hi

I have done my graduation from Warwick.
I have been selected in an institute in India, they require a migration certificate from the university I attended last.

Does, warwick or even the UK have anything known as migration certificate, if yes then where can I get it from?

The form expands migration certificate as follows

"Final Year Marksheet/provisional certificate of passing/Internship completion
certificate/Migration Certificates issued by University/Institute authorities should be handed over to the Academic Section, within three months of joining the course."

That means the official transcript of studies will suffice right? Which I have with me along with the degree

Any help would be appreciated

Thanks a lot in advance
