Moving from Exchange 2003 to Exchange 2007

[Disease]

Is there an easy upgrade path from 2003 to 2010?

No youd have to migrate but thats easy enough i you are moving to a new server(virtual or physical) just not the same box - although thats possible but a bit more long winded.

im affraid there is no inline upgrade option, you have to migrate the mailboxes to another server

I have a new server for my email, my current server is EX2003 with a single core 3gig Xeon with 2gb ram and it's really struggling now. I have purchased a new server with 2 2.33 Quad Core Xeons and 8 GB ram and was going to put 2007 on it and transition over but now I am thinking I might as well just make the move to 2010.

To clarify, you have to build a new server and move the mailboxes. You cannot do an in-place upgrade, but 2010 will co-exist with SP2 perfectly fine.

However one thing to note. You really need a 2008 domain controller (2003 still works) just 2008 is more efficient and outlook connectivity is vastly improved.

A move straight to 2010 would be advisable. however i would vastly increae the ammonth of ram required.

Exchange 2010 server role

Multiple roles (combinations of Hub Transport, Client Access, and Mailbox server roles)
10 GB
10 GB plus 3-30MB per mailbox (4 core server)

14 GB plus 3-30MB per mailbox (8 core server)

I would also seriously inspect hard drive configuration and mail database setup.

I plan to upgrade all my servers to 2008 over the course of next year, from what I understand you can do a straight upgrade from Server 2003 to 2008.

Thanks for the advice I will certainly take it onboard.

You can do an inline upgrade from 2003 to 2008. (im not really a fan of doing this)
And I certainly wouldn’t try it for DC's.

I thought in order to have a 2008 Domain controller you have to upgrade all cuurent 2003 DC's to 2008. I am sure that when I went to install a new DC using 2008 it said that I could not do it until all current DC's were 2008, I am probably wrong in that but I am sure that's what it said. Anyway I seem to have partly hijacked this thread sorry.

If that were the case how could you install the first 2008 domain controller?

You would have to install 2008 server add it to the domain as a domain controller this would involve upgrading the forest and upgrading domain. Domain prep tools.

once that one is installed you can gradually go round replacing the remaining dc's.

However once one is installed it will automatically upgrade the adm files to admx.

Hope this helps

Thanks Phil, I knew it didnt make any sense.

The intention is to roll back to Exchange 2003 until the summer. As with most IT in schools so much to do and so little time to do it. Rest assured we will be moving, just not right now.
