Moving from Exchange 2003 to 2007

We have an Exchange Enterprise 2003 server on an Windows 2003 server and do not have many issues.  We have about 100 users and about 10 remote users who use WebAccess and we are considering going to Exchange 2007 but have no real requirement or reason to go to 2007 at this time.  We wanted to see what people think of Exchange 2007 and is it worth it to rock the boat just to say we moved to 2007or should we stay with Exchange 2003 for awhile since it fills our needs and we have no issues?

Exchange 2007 has a number of new and improved features but it really depends on your situation. One thing you do need to consider is the Exchange 2007 is only supported on 64 bit systems running 64 bit Windows 2003.

As you probably know you can't upgrade to Exchange 2007 so both of these points mean you need new hardware. Do you have a planned hardware refresh? If so I'd probably link it to that but you don't want to still be supporting Exchange 2003 after 2009 as this is when mainstream support is scheduled to end.

We're linking ours to a hardware refresh plus the requirement to move a number of our mailboxes from remote Exchange servers to our global data centre but we're a big company and therefore need to wait for the powers to be to decide on things.


On the number of users that you have I would struggle to justify the switch to Exchange 2007. It is an unfinished product as far as I am concerned, but will be fine once the Service Pack is released towards the end of the year.

If you have a stable environment then why change?
If you are thinking of a change then make sure you evaluate it carefully to ensure that any of the missing features and options are not an issue for you.
Also ensure that any third party tools that you are using are compatible or have updates available for Exchange 2007.
