Hello wondered if anyone could give me some advice. I have a Windows
2000/2003 domain running Exch 2003 OK and I have 2 Windows NT 4 domains
running Exch 5.5. I am about to migrate them over to 2003 and wondered what
the best method is.

I've been running the ADC connectors between the domains OK and have the
users in my AD.

My plan was to install a new server running Win2003 and Exch 2003 and join
that to the existing 2003 domain and enable the users in AD and then move
the mailboxes from the old 5.5 server to the new 2003 version. Will this
work as the 5.5 server will be in an old domain. Will the SID's be
different between the NT and AD? What about Public Folders?

As this is only for about 15 users I was also think of going down the
EXMerge route and then just import the data into new accounts.

In your case it might be easier to use ExMerge for users and copy PF
contents you want to save to PST files in OL, manually drop them on new
folders on new E2k3 server.

Otherwise, you are looking at setting up two-way external trusts, running
ADMT (migrate SID with the account), cleaning up the ad since ADC has
already brought over objects, Move Mailbox, replicate PFs. The process for
E2k and E2k3 is much the same, but with only 15 user mailboxes you've got to
ask yourself which process will be easier? For large scale migrations the
ExMerge option is not valid.

In your case it would be easier to use ExMerge and copy PF content to PST in
outlook, transfer to new server.

Otherwise, you are looking at setting up two-way trusts, using ADMT to
migrate accounts with SID, Moving mailboxes, etc. which can be a long
process. The process is very similar between E2k and E2k3.
