Thats a pretty big tank, about 380 litres roughly according to your measurements.
Very doubtful you can move the tank by yourself, even when empty of everything.
I have a 350 litre tank in garage, I definitely could not move that by myself, had to get a friend to help lift it and move it.
(and I am not exactly a 6 stone weakling!
)
Your best bet, is to empty the entire tank, and you'll have to ask a friend or neighbour to help move it, should be straightforward since only a few feet presumably in same room.
I fear, if you try to move it yourself by dragging it on cabinet or stand you will do yourself an injury of strained muscles or worse, or cause damage to the tank.
Always better safe than sorry, please try and get someone to help you, ask nicely, beg, plead or bribe with cups of tea should do the trick.
