Purchased AWS reserved instance in wrong region I purchased AWS reserved instance by mistake in Mumbai Region. actually, I need that in N.virginia region.

I contact AWS support center and they told "switching region of AWS reserved instance is not possible"

Is there any way to switch region? Please help.
If you have done payment of your reserved instance then you are unlucky. now you have only one option Sell your reserved instance in AWS marketplace.

But If you till not done payment then you lucky, I suggest don't do payment till next billing cycle. AWS by default cancel your reserved instance if you don't do payment after the end of the month.
