Downgrade iOS 9 to iOS 6

Nope.

This will never, ever be possible.

And if it ever could be possible you would find that there are virtually NO MORE third party apps initially available for any old iPad models running iOS 10 and earlier.

NO Apps!

So, not a good idea.

Your 2011, iPad 2 will be 10-years old by April 2021!

Your iPad is too old now.

Sorry.

If you need/want an iPad with an up to date iPadOS with access to current, updated apps, then you really need to seriously consider a new iPad model OR a much, MUCH “newer” and less expensive, used iPad models, from better known, trusted Apple product/device retailers/resellers, capable of running the latest iPadOS versions.

There are plenty of newer, older iPad models that can run the latest, current versions of iPadOS.

It is time for a new iPad.

A WHOLE LOT has happened with iPad/iOS/iPadOS in the past 10 years!

Sorry & Best of Luck to You!

You can't. Unless otherwise noted, downgrading is only possible when going from a beta to the current release.
