What is Compatibility Testing?

From it's name, Compatibility testing is for compatibility. Then what does the "compatibility" mean?

For general devices, it's "The characteristic of data processing equipment by which one machine may accept and process data prepared by another machine without conversion or codemodification."

For hardware, it means " the ability of a subsystem (e.g. memory) or an external device (e.g. terminal) to be substituted for the originally designated equipment."

For software, compatibility is " the ability of a computer to directly execute program code that was compiled, assembled, or written in machine language for another computer."

For a piece of new software, compatibility means " the ability to reproduce the behavior of its predecessor, in particular to accept the same input formats."

So for compatibility testing, it depends on what the AUT is. And you should choose different way to test different AUT or DUT. But typically speaking, to test software compatibility, you need verify that the software follow the definitions above.
