Upgrade from exch 5.5 to 2003

I have a single site single domain running exchange server 5.5 SP4 on a windows 2000 SP4 server.
I need to make the same server(hardware) into a windows/exch server 2003 environment.
I have 3 other DCs that are running 2003 server on the same domain.

Because of previous OS issues with the 2000 server, I would like to do a clean 2003 server install on a new HD.

I do have a few books on upgrading and took a short MS class so I have some idea of the differences b/n 5.5 and 2003 and how the upgrade works, but this is somewhat of a special case bc its a clean HD and OS install.

Can someone please recommend a procedure for this task? Personal experience in this situation would be great!
Thanks!
Joe

Basically - install Exchange on another machine - move everything to that machine. Remove Exchange correctly from the old machine, so that it has gone. Wipe and rebuild the old machine, move everything back.

I have an article on Exchange 200x swing migrations.
http://www.amset.info/exchange/migration.asp

For Exchange 5.5, look for the Ed Crowley Server Move method in Google. (Ed Crowley is a long-time Exchange MVP who first wrote down this method of moving servers).

The key thing is to make sure that you remove Exchange correctly.
The slow bit will be getting off the old server. Once you are on to Exchange 2003, moving servers is easy.

exchange 5.5 does not work on windows 2003.
so the option would be to remove exchange 5.5 from this server and then upgrade windows 2000 to windows 2003 and then install exchange into the same exchange ORG.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

the you need to rule out the windows 2000 upgrade and just install a fresh copy of windows 2003. but then also in any of the cases exchange 5.5 cannot run on windows 2003 and has to be removed or you will have to install this new exchange 2003 server on a different server.

i said in this original statement that i DO NOT want to do an OS upgrade on this hard drive.
i do not understand what you mean by  "has to be removed or you will have to install this new exchange 2003 server on a different server."
it basically will be a new server, but i have an existing (5.5) Exch IS.

what i understand from the above statement is that you want to install exchange 2003 on the same box that has exchange 5.5 installed

is that not correct?

same box yes- hardware only... but then i added

"Because of previous OS issues with the 2000 server, I would like to do a clean 2003 server install on a new HD."
had some viruses and other crap on the server, just dont want to deal with any existing 2000 stuff. Completely new HD going to be in the box..only want to take the IS out of the original HD.

>only want to take the IS out of the original HD

what do you mean by that?
so you are saying that the old server hosting exchange 5.5 will be touched and you will be installing exchange 2003 on a new hardware

it means that the only data that i want to use from the hard drive that is in place now is the 5.5 information store. I am going to remove that hard drive and put in a brand new hard drive into the same box.
then do the server 2003 install.
my question is, how can i then set up the "new" machine with exchange server 2003 using the preexisting 5.5 IS.

You can't forklift an Exchange 5.5 information store.
From memory you have to be at a minimum of Exchange 2000 SP3 with a certain hot fix or the latest rollup to a forklift installation.

Your better option would be to swing migrate using another machine as a standby machine.

when you say install exhange on another machine, do you mean 2003 or 5.5?

SembeeCommented:
Up to you. I would probably do Exchange 2003, it is much nicer to work with, so you would want to get up to that version sooner rather than later.

yes, Sembee is right. E55 databases cannot be forklifted to e2k3.

your options would be to move over all the data from exchange 5.5 to the exchange 2003 servers and then de-commision it or created a new Exchange 5.5 server and move data to it.

Read the crowley method, but ended up learning the most from following the MS KB articles listed here...If I had a bigger site I wouldn't have been able to do this method (luckily, not too many large exchange sites still on 5.5)

Some precautionary stuff :  http://support.microsoft.com/kb/555262/en-us

this is a comparison of the methods:
http://support.microsoft.com/kb/327928/en-us

and I went with the Exmerge method described in this article.

thanks for the help
