can you update any Ipad? my version is one of the older ones
Sorry, the iPad 2 cannot be updated beyond iOS 9.3.5 or 9.3.6 depending on the model.
What devices can run iPadOS 14?
If you have a model older than this, you can still update to the latest version compatible with that device, even after your device stops being supported.
All iPads have a certain Apple support life.
Anywhere from 4-6 years, or so.
Third party apps developers will continue to supporting unsupported Apple devices for another, additional two years, or so.
Your iPad is too old for any more upgrades/updates.
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, locally or online, capable of running the latest iPadOS versions.
There are plenty of newer, older iPad models that can run the latest, current versions of iPadOS.
Sorry & Best of Luck to You!
