imapsync, Cyrus and public folders

I'm trying to migrate a Cyrus installation from one server to another.
I've copied a test account using imapsync, but all the public folders
are copied into the destination user's folder hierarchy. On the
original:

/cyrus/mail/Customers/xxxx #public folder hierarchy
/cyrus/mail/user/xxxx/Drafts # user folder

On new server after copying with imapsync:

/cyrus/mail/user/xxxx/Customers
/cyrus/mail/user/xxxx/Drafts

Command used:
imapsync --host1 a.b.c.d --user1 xxxx --password1 xxxx --host2 v.x.y.z
--user2 xxxx --password2 xxxx --ssl1 --ssl2 --syncacls --port1 993 --
authmech1 PLAIN --port2 993 --authmech2 PLAIN

If imapsync can't handle this, what's the best way of moving the Cyrus
data from one server to another, given that they use different
versions of bdb? rsync and db_convert?

Thanks,
Keith

imapsync can.

From the FAQ :
================================================== ====================
Q. I want to exclude a folder hierarchy like "public"

R. Use

--exclude '^public\.'
or maybe
--exclude '^"public\.'

In the example given the character "." is the folder separator,
you can ommit it. Just take the string as it appears on the
imapsync output line :

From folders list : [INBOX] [public.dreams] [etc.]

Adapt this with "Custumer"
