The focus centers on upgrading dated Apple tablet devices operating on a specific, legacy operating system version. This involves transitioning these devices from iOS 9.3.5 (or potentially earlier versions compatible with the same hardware) to a more current and supported iOS version, if feasible.
Addressing this upgrade scenario is important for several reasons. Primarily, newer iOS versions provide enhanced security features, mitigating vulnerabilities present in older, unsupported operating systems. Further, software compatibility becomes an issue over time; many modern applications may not function correctly, or at all, on older iOS versions. Historically, device obsolescence has always presented challenges for users wanting to retain functionality.
