THere's lots of opinions on this one...the rule of thumb you always hear thrown around is that you can move a bee hive 2 feet or 2 miles, with everything else in between being a problem. The theory being, 2 feet is a short enough distance that when they don't find the hive where they expect it to be, they start a circular search and find it rather quickly, while 2 miles is an extreme enough change to prompt them to re-orient when they exit the hive.
THe problem being is that the distance most people want to move a hive is usually more than two feet, and less than two miles. :?
What I, and i think most folks on this forum do, with good success is after the move place either a branch, or piece of wood in front of your entrance, not totally obstructing entry, just rerouting them. This helps to que the bees that something has changed and gets them to re-orient to the new location.
There are others that would make the move by taking baby steps over multiple days, in my opinion, more trouble than it's worth....especially for moving a meter....I think you'll be fine. You may not even need to use the branch trick, but it's so easy, why not?
I usually leave the obstruction for a couple days or so, then remove it.
Good luck! :)
