Not exactly like you describe the migration procedure.  You will have
to manually specify all the mailboxes that reside in the source IMAP
server (see the "folder all ..." line below).  A possible configuration
file to do the job:

--BEGIN--
account src user:pass at server.src
  folder all mbox1,mbox2,foo/bar,foo/qux

account dst user:pass at server.dst

filter migrate
action rcopy dst $_

job migrate all
--END--

You could also do "rmove" instead of "rcopy", but "rcopy" and then
"delete" is the safer solution (if all have gone well you then run a
"delete" filter through all the mailboxes of the source IMAP server).

NOTE: You MUST apply the attached patch against imapfilter 0.9.2
to do rcopy/rmove with the default variable "$_".  I will release
0.9.3 soon with this correction included.  Patch like this:

  tar zxf imapfilter-0.9.2.tar.gz
  patch < patch-0.9.2-1
