Hi,

We have one active directory 2003 native domain and the single existing Exchange organisation with two administritive groups has recently been consolidated onto one front-end and two back-end Exchange 2003 installations.

The Exchange Organisation has been in existence for many many years starting as Exchange 5.5, then 2000 and new 2003 versions of Exchange and there were around 15 mailbox servers and admin groups at the peak.

There are a number of small underlying issues remaining due to the consolidation including multiple redundant System Folders (OWAscratchpad, SCHEDULE+FREE BUSY, StoreEvents, etc).
We would like to take the opportunity of the 2007 install to "clean-up� the Exchange Organisation and provide a stable platform for the future by creating a new Exchnage Organisation.

How can I install Exchange 2007 into a new Exchange Organisation whilst retaining the existing 2003 version until I have migrated all the mailboxes.

Thanks in advance.

Billy

It's pretty hard because e2k7 will have to be part of the exchange org. You will still have to migrate PF, free/busy etc over to e2k7.

You could always create a brand new forest and use Quest tools (or others if they exist, etc) to migrate user accounts and mailboxes across. It seems pretty drastic to me when you've only stated that this is a "clean up" exercise of a few unwanted system folders. Is there actually a problem you are trying to solve? It doesn't sound like there are actually any issues.

I had considered the new forest route but I agree it's drastic given the following examples of the small issues we are experiencing.

The Exchange Organisation currently houses around 600 mailboxes but this is scheduled to increase to 2500+ VERY soon.

A number of the current 600 users experience difficulties in scheduling meetings as there Outlook Client (XP, 2003 online or 2003 in cahced mode) reports free/busy problems. The usual methods to recreate free/busy folders have not mitigated the problem.

Also we had a small number of really old public folders that refuse point blank to replicate unless they are exported/deleted and recreated on a different server.

I was keen not to expand the number of mailboxes whilst there were obvious problems so had thought that a new Exchange 2007 Organisation may allow me to move everyone to a new and clean platform without the underlying issues.
