If you are the sole copyright holder, that is very easy.  The fact
that you have released the module to some people (the general public)
under one license does not bar you from offering it to anyone else
under a different license.  I have done the very thing you ask about,
except with C code; to cover myself and my employer on questions of
propriety, I added a comment on the lineage at the start of the files
I reused.

If you want to be safe, retain a qualified lawyer to advise you on
this issue, especially on the question others have mentioned about
original ownership of the copyrights.  You could try to ask the
company's lawyers, but they owe their duty to the company, and so may
not give the answers that serve you best.
