If you are the sole copyright owner, of course.  You can distribute your
work under any terms you wish.  The terms under which you have previously
distributed it are irrelevant.  If you are not the sole copyright owner you
must get the agreement of all the other owners.

I am confused by your question.  The fact that a work has been distributed
under the GPL is no bar to its copyright owner distributing it under other
terms.  The license is a unilateral grant from you to others.  It does not
bind you in any way.
