Hello Aspirant,
If you have been admitted to a college earlier and want admission in another college now then you don't need to worry about it.
You can apply for TC from that college. Your SLC will be canceled and a new College Leaving Certificate will be generated by the college. The migration certificate will be returned to you.
I hope it helps.
Thank you
