I lifted the head of my Innova longarm off the frame and set it down on a flat dolly, which I wheeled into a closet. Later on it was wrapped in blankets and rode from Oregon to California in the back of my car.
I took the frame apart by myself, taking pictures and making notes as I did so. I labeled the parts by writing on masking tape, and I used zip ties to hold things together that I wanted to stay together and baggies to contain nuts and bolts, all labeled so I'd know where they belonged. The pieces came to California in a U-Haul that I drove. Movers carried the pieces to my upstairs quilt room.
When it all got to California, I reassembled the frame pretty much by myself, in reverse order from how it was taken apart. My adult son came over later to help insert the 12' long bars, tighten bolts, help me level the frame, and lift the head onto the frame.
Altogether, easy peasy. But not all longarms are as user friendly to take down and reassemble as the Innova.
