You always run the risk the problem of an empty pool rising up, and cracking.
"Water acts as a stabiliser that weighs the pool down when it's in the ground, so when you take that water out, it could 'pop' out of the ground or cause the walls to cave in,"

I did it to retile our pool in the dry season.
No problems.
If its not to large fill it with some dirt being careful to have Pipes sealed and marked.
