How do I upgrade my iPad to iOS 11.2

what model is your iPad and what iOS are you running right now?

if you try to update and it tells you that you're iOS is up to date then most likely you are at the end of the road as far as updates go

Chance are your iPad model is too old, now!

Sorry.

If you need/want an upgraded iOS/iPadOS with current, updated apps, then need you to seriously consider a new iPad model OF a “newer” , used iPad model capable of running the latest iPadOS versions.

There are plenty of newer, older iPad models that can run the current iPadOS 14 versions.

Sorry & Best of Luck to You!

Whether you are able to update your iPad to a newer version of iOS/iPadOS will be dictated by your iPad model - and the currently installed version of iOS. You can find this information here:

Settings > General > About

Not sure which iPad you have? Identify your iPad model.

Here is a list of the highest version of iOS supported by the older models of iPad (for simplicity - “generations” are shortened to a number) that are restricted in their ability to be updated:

iPad1 - iOS 5.1.1

iPad2, iPad3 and iPad mini1 - iOS 9.3.5 (WiFi Only models), iOS 9.3.6 (WiFi & Cellular)

iPad4 - iOS 10.3.3 (WiFi Only), iOS 10.3.4 (WiFi & Cellular)

iPad Air1, iPad mini2 and iPad mini3 - iOS 12.4.9

Newer models, not appearing in this list, are all able to be updated to the current version, iPadOS 14.2.
