Don't think a healthy toad will die of shock over a tank transfer. Set-up the new tank (substrate etc.), move decor to it (clean if needed) and then transfer toad. You do not need to grab her if undesired. Can use a small clean (no chemicals) pail or plastik container; place in toad's front and coax her butt in. Then cover with hand and place container on new tank, letting frog get out at will. Avoid feeding toad first couple of days and let it set-in... done !
