hi everyboy,
as i have to start migration work in the following senerio,
(after clear understanding migration of exchange 5.5,that is why i am
here to.. )

At this point I know about migrating single 5.5 org to 2003,
trust establishment,ADMT,ADC-CA,,joining Exchange 2003 in to existing
5.5 org, move mailboxes.

but clear picture is needed where same named domains,and 5.5
organizations are present.
how to establish inter org CA between same named(no dns infrastructure)
domain/org.....?

below are the details,
hope some could put me on right track...
thanks..

senerio
no of locations =N
(not a matter,If we know about two of them, steps will be repeated for
Nth office..correct me if i am wrong)

Goal: To migrate from multiple exchange 5.5 organizations to single
exchange 2003 org

Details:
location1

NT Domain name (Netbios) :myoffice
Exchange Organization Name:myoffice
exchange server name:myoffice1
internal smtp address:myoffice1.office.org.in
external SMTP Adress:diffrentname.org.in

Ims config: forwords all mails to smart host

at office2

NT Domain name (Netbios) :myoffice
Exchange Organization Name:myoffice
exchange server name:myoffice2
internal smtp address:myoffice2.office.org.in
external SMTP Adress:diffrentname.org.in
Ims config: forwords all mails to smart host

location N

NT Domain name (Netbios) :myoffice
Exchange Organization Name:myoffice
exchange server name:myofficen
internal smtp address:officen.office.org.in
external SMTP Adress:diffrentname.org.in
Ims config: forwords all mails to smart host

all offices are reachable within WAN.

each office is a diffrent NT 4 domain but have same names
each office is a diffrent exhange 5.5 organization but have same names
Smart Host is Handling delivery of incoming mails to appropriate
server.
Smart Host is Handling outgoing mails.
 
 
 

1. Exchange 5.5 to Exchange 2003 inter-org migration questions

2. Remove First Exchange 2003 in a Exchange 5.5 Org with 2 Exchange 2003

We need some guidance with the next step:

1st. We installed an Exchange 2003 STD SP2 (Exc2003 A) in a old box
with Win2003STD SP1 to migrate Ex5.5. and until now, they are working
fine, but we need to dissapear this box so...
2nd. We get a new box with Win2003 STD R2 SP1 and installed an
Exchange2003 STD SP2 (Exc2003 B) joining the org and moving all the
mailboxes, PF and so on...

We have two Exc2003 behind an Exc5.5...ugly but it's what we have!

So, we need to retire the first Exc2003 (Exc2003 A) and get the email
flowing from the Exc2003 B to the Exc5.5 until we get the ISA 2004 up
and running to retire finally the 5.5/NT4 box.

Ideas???

Thanks
Damian Serpentini.
