Hi all!
Doing some preimoptive work for the introduction to Exchange Server
2003 SP2.
Environment:
- 20+ Exchange Server 5.5 Servers (NO USERS, still migrating public
folders)
- 15+ Exchange 2000 Servers SP3
- ADC from 5.5 servers to 2000 servers.
- Currently = Mixed Mode 2000
To do:
- Introduce 2 x 2003 Front-End and 2 x Back-end 2003 servers to get a
Dev POC up and running.
Problem:
- According to " http://support.microsoft.com/kb/823601 " I 'must'
upgrade all 2000 ADC connectors to 2003 ADC connectors before the
first 2003 exchange server can be installed into the Organization. If
they are not upgraded, you will be forced to install into a new
Organization.
....and quote:
"If you introduce Exchange 2003 into an existing mixed organization
(one that has both Exchange Server 5.5 and Exchange 2000 computers),
you must upgrade the existing Exchange 2000 ADC computers to the
Exchange Server 2003 version of ADC before you introduce the first
Exchange 2003 computer into the environment."
....and:
"Eventually, you must upgrade all ADC services before you install the
first Exchange 2003 computer. Either perform an in-place upgrade of
all ADC services that are older than Exchange 2003 before you install
so that all earlier Connection Agreements are phased out. Or, perform
fresh installations of the Exchange 2003 version of ADC, move all
existing Connection Agreements to run on the newly installed ADC
service, and then remove the Exchange 2000 ADC installations."
Questions:
1..Is this actually a requirement and I will not be able to install a
Exchange Server 2003 box into the current Organization?
2..Will the installtion actually allow me to install and this is just
a recommendation? And how will this effect the public folders?
Remember there are no users on exchange server 5.5 at this point, just
public folders.
Cheers!
