Default Mix 89 with 87 before changing?

Have run only quality name brand 89 octane since new. Was thinking about running 87 for a tank to see how the engine performance reacts. Should I run a tank of 1/2 89 and 1/2 87 before going to a full tank of 87? Was thinking a gradual step down might be easier for the computer to adjust. Thanks.
