Moving from Exchange 2003 to Exchange 2007

[Geek_of_HeathMount]

Morning all
I'm after an exchange expert as we're in the process of moving from 2003 to 2007 and there's lots of things that keep breaking. My gut feeling is to wipe the 2007 install and start a fresh but I want to talk to some one before I do.

Thanks guys

What have you done so far, what errors are you getting?

Are you doing an in place upgrade or a parallel one?

I had a few problems with mail delivery over 2 servers when I did this.

Hi guys just to confirm a few things

These are the instructions i followed
Transitioning from Exchange 2000/2003 to Exchange Server 2007 Part 1
Transitioning from Exchange 2000/2003 to Exchange Server 2007 Part 2
Transitioning from Exchange 2000/2003 to Exchange Server 2007 Part 3

1. We have 2 exchange servers 2003 & 2007, so we are doing this in parallel
2. I have four issues which i'm concerned about

a. Outgoing email is now starting to build in the 2003 queue
b. The Outlook Anywhere doesn't work as the settings have not gone across and i don't know why
c. When opening the management console on 2007 it tells me that i need to turn off the compression for the 3 default exchange sites using the IIS manager. The problem is when i do this it then tells me that the relevant back office file is missing.
d. My test mail account on 2007 can not send email

Hope this helps

Yes I had the same problems with delivery mail, I seem to remember the exchange testing tool was very useful in diagnosing problems with mail flow.

In the end I just kept my 2003 server going though, it doesn't seem any different.

Are the ports open on the firewall for the new server? Is it the same or different ip to your exch2003 box?

[Geek_of_HeathMount]

The ports are the same as the old exchange server
The the firewall knows nothing about the new server. I was under impression that everything went via the routing group and therefore went via the existing smtp connector?

We had an issue when moving our exchange 2007 system onto R2, problems with routing mail. we spend hours checking ports/firewals etc.

we discovered(sorry i cant find the link again) that 2007 isnt supported on R2, you either need to upgrade exchange to 2010 or migrate to a windows server 2008 box

hope this helps

I'm happy to blow 2007 and MS server 2008 R2 away.
But will i damage Exchange 2003 in the process???

Our 2003 server was fine and not effected when I've tested this a few times.

Moving From Exchange 2003 to 2007 can be a fairly easy process. We have done this several times. We have also moved from 2003 to 2010 and 2007 to 2010.
We are George Spencer School and also run Advanced IT Services. Please feel free to contact me if you have any questions regarding your move. pdixon@advanceditservices.co.uk

P.s. I would recommend going straight to 2010

thanks for all the help guys, but i even had an exchange expert in and he couldn't figure what went wrong.
so we're rolling back to 2003

Noooo... exchange 2007 is far far far better... coudl you tell me in a bit more detail the problem so i can have a think...

or even where is your school?

Maybe some screenshots would do good, too? I don't see the logic about pernamently moving back to 2k3. Tried a clean exch 2007 install on a clean 2k8 (not R2!!) install? Is it virtualised? we have a virtualised setup here and it's fine, but I have heard it run into problems on vm's.

The only time i have ever hit problmes is if a 2003 machine has been taken off without actually removing it. Even then it isnt that hard to clean it up manually.
