2 questions - Migrating Exchange 5.5 to 2003

[beerhunter2]

1) Will Exchange 2003 run on a Windows 2000 member Server?
- If yes, are there any gothca's I need to be aware of?

2) When migrating the mailboxes from the 5.5 Information Store, will the Information Store in 2003 grow, shrink, or stay the same?

Help! I've fallen and I can't reach my beer.

Grow probably since you'll lose Single Instance Storage when you do the transfer.

Figure on it at least doubling. Which will be a bit of a problem if you only have std. edition.

Thanks for the response ntinlin.

Sounds like I'm hooped then, until SP2 comes out anyway.

You could always use exmerge to dump out the mailboxes to PST's and give the users those to start kind of fresh with the new system.

Thanks Neill. I'll run that by management and see what they say.

Do you have any insight on question 1? I read somewhere that I still need to run Forestprep, just as if I was on Windows 2003 server. Is this true? If it is, does Forestprep come with Exchange 2003 standard edition?

Yes exchange 2003 will run on W2k. it will tell you during installation that this is not mean for this OS etc... but it will work,,

You should really use W2K3 instead..

Hi beerhunter.

You'll need to run XC2003 setup /forestprep and setup /domainprep but the setup takes you through that and checks to see that it has been done.

I didn't think 5.5 supported SIS did it, if not then the DB shouldn't grow during the migration. It might even shrink as it will be defragged etc.

Thank you all for your response. I believe I now know where I stand, and what I need to do.

Nickferrar - Yes, 5.5 does support SIS (unfortunately for me)
