Add your new nnml groups to the split method, delete the entries
pointing at your nnfolder groups, use gnus-summary-respool-article to
send old articles through the new split method.  I assume that the
process mark will work with -respool-article. 

I'm not sure if xref's will be respected; I don't see why you'd need
xref's for old mail, though.  Anyways, moving mail using
gnus-summary-move-article is guaranteed not to respect xref's, so this
is better if only for the uncertainty.
