If your current switch is running LanLite (light), you generally cannot upgrade to LanBase images without a license change, though 2960s usually ship with LanBase natively. Verify your current license level:

Cisco IOS 12.2(44)SE6 is a mature, stable release from the late 2000s/early 2010s. It arrived after several bug fixes and security patches. For the 2960 series, this version is often considered a "golden release" for environments that do not require newer features from 15.x trains.

A common misconception is that you can load a newer IOS 15.x image onto a switch running this binary. You cannot.
The original 2960 (non-Plus) hardware stopped development at IOS 12.2(55)SE. The 122-44.se6 is often the last stop before the final EOL release (which was 12.2(55)SE10). If you have a switch running this image, you are stuck in the IOS 12.2 train permanently. If your current switch is running LanLite (light),

For networks needing StackWise-48 or dual software, the 2960-S line with 15.x is superior. For pure Layer 2 access with no growth, 12.2(44)SE6 remains usable. Cisco IOS 12
Given that 12.2(44)SE6 reached End-of-Life (EoL) in 2013, running it in a production environment requires compensating controls.
