updating to a better ios software , thats not available for your ipad model

iPad2 cannot be updated beyond iOS 9.3.5 (WiFi Only models) or iOS 9.3.6 (WiFi & Cellular).

Apple ended update support for these devices in September 2016, along with iPad3 and iPad mini1. None of these models can be updated to iOS 10 or later versions, as the internal hardware does not meet the minimum technical requirements for new versions of iOS/iPadOS. The 32-bit architecture utilised by these devices is obsolete, having been replaced by 64-bit systems for which later iPad models were designed to support.

Many App Developers have also dropped support for older devices and iOS versions preceding iOS11/12/13 - and have withdrawn older versions of their Apps from the Apple App Store.

If Apps that you need to use now have higher minimum iOS-version requirements, your only option is to replace your iPad with newer model. Of current models, even the entry-level iPad7 will outperform you old iPad in every respect; all current models support iPadOS 13.x and the majority of available App titles.

I hope this information is helpful - if only in clearly stating your current options.

No. The iPad 2 is nearly 10 years old and incapable of running anything newer than iOS9.3.5(9.3.6 if it’s cellular)

It lacks the hardware to run the software
