I would give at least a few days. When he seems to be back to normal, I would go ahead and feed (unless you have particular feeding day, then I would wait until the next one). I would also say it depends on age of snake and time with you a little. If he's established otherwise, I would not think you would have to wait as long. If established, I would go back to a normal routine of handling, etc. after the first meal in the new home is digested.
