This colony had been living in a conventional 8-frame, deep Langstroth hive that had been sitting in this exact location. I moved the colony into a Bee Tree Hives Vertical Preservation Hive which is comprised of two 4-frame deeps. The four center frames went into the top hive body, and the four outer frames (none of which had brood) went into the bottom hive body.

It was interesting that the foragers that had been out when I started this process - which I could identify because they were returning with pollen loads - flew right into the new hive. (An indication that "GPS location" and scent are preeminent over sight when returning to their hive?)
