The copyright owner of the software (generally the person who wrote it) can do
anything with it that he chooses.  He can't retroactively revoke the GPL from
copies already distributed, but he can re-license his own work in any way that
he chooses from any date forward.

If  he accepted outside contributions from others pursuant to the GPL then he
will have to either get those outsiders to grant permission to re-license the
work, or just not use those contributions with the newly-licensed software.

Either way, though, it's up to him to determine how he wishes to license his
own software.
