[Dovecot] Migrating from imapd to dovecot - how to keep user's Mail folders

[Patrick - South Valley Internet]

Hi all,

We're migrating off our current mail server with runs postfix and imapd 
on an AIX machine to Postfix and Dovecot running linux.  Our customers 
have a lot of IMAP folders with folders they configured, which are 
currently located in their /home directory on the current mail server.  
The new mail server will have them at the same location.

How do I configure Dovecot so that when a customer connects via IMAP 
using their favorite e-mail client, that the folders will be there?

Thanks in advance.

Patrick
