When to Switch from Mixed Mode to Native Mode

Hello,
I am doing a Migration from Exchange 2000 to Exchange 2003 using new
hardware.

My servers now look like this:
Windows 2000 SP4 server with Exchange 2000 running as a DC and GC
Windows 2003 server with Exchange 2003 SP1 running as a DC and GC

These are the steps I have completed:
Added the Windows 2003 server as a DC. (I ran thought the entire process;
But just want to write it out.)
Changed to â??Exchange Native Modeâ??
Ran Exchange 2003 setup/forestprep
Ran Exchange 2003 setup/domainprep
Installed Exchange 2003 (From the â??Exchange Server Deployment Tools SP1â??)
â?¢ I selected to â??Deploy your first Exchange 2003 serverâ??
â?¢ Then â??Upgrade from Exchange 2000 Native Modeâ??
Installed Exchange 2003 SP1

I started moving a few user mail boxes to test the waters and everything
looks great.
Then I start reading more on how I going to move the public folders and here
is where I saw the problem.

When I went to the properties of the organization to select â??Show Routing
groupsâ?? and I noticed that the Exchange Operation Mode was still reading
â??Mixed Modeâ??. Now I know that I changed this!

Could this be a mistake? What ramifications could happen if it is in â??Mixed
Modeâ?? and I change it to â??Native Modeâ??? Is there a place in ADSIEdit that I
can check to see if this is set? Any Advice would be much appreciated!!!

Thanks
James

By default, Exchange 2003 is installed in mixed mode, so I thing that was
what happened.
Exchange 2003 native mode supports exchange 2000 servers, so you won't have
any trouble changing it to native.

I was just concerned because under the install I selected "Upgrade from
Exchange 2000 Native Mode".
And had thought that so AD stuff might not have gotten created because I
selected this.
I am going to try to do the change tonightâ?¦
Thanks for your help,
James
