Hi, I just migrated from dovecot 1.0.rc29 to 1.1.7, from Sparc platform to Intel, it went very well. In the process I merged folders and excluded folders from being copied. User rights on folders were kept/set. I thought I'd share my migration script with you folks. If there's an interest to put it on the wiki I can do that, but I'm not sure in what page. Use it as a starter if you need to do this yourselves. Prerequisites:

• User names are local unix accounts
• Old server's /home must be mounted with nfs
• Structure and user names must match between the two systems
• Source dovecot must be at least version 1.0.x
• Destination dovecot must be 1.1.x
• Only dovecot data folders and files are copied, neither dovecot indices nor Sieve scripts etc.

Here it goes, have fun! /Peter

#!/bin/sh

Migrates dovecot Maildir folders and settings from older dovecot on

old server to new dovecot on new server.

Prerequisites:

* User names are local unix accounts

* Old server's /home must be mounted with nfs

* Structure and user names must match between the two systems

* Source dovecot must be at least version 1.0.x

* Destination dovecot must be 1.1.x

* Only dovecot data folders and files are copied, neither dovecot

indices nor Sieve scripts etc.

rsync would be simpler.
