Doing export with compress = y is generally a BAD idea. It results in an import file that defines a single extent large enough to hold all your current extents. This could make it hard to find a single file large enough in the target tablespace, destroys your options for a 'uniform extent' strategy, could waste a huge amount of space (which you can, fortunately reclaim) and is not needed to reduce performance-related fragmentation.
