Hi All,

We are trying to move mailbox from exchange 2000 to exchange 2003 across
different administrative groups and different domain.
Our AD is win 2000 and most of the exchange servers are exchnage 2000 SP3 and
above and one server is Windows 2003 SP2 & exchange 2003 SP2 and some
countries have EXchange 5.5. Both AD and Exchange run in MIX mode.

We have one Exchange Organization ( *.@abc.com) but we have so many Exchange
Administrative Groups and connected via routing connector. There are
different domain in different branches in different countries. Let say in
Singapore, they will use domain name like abc.com.sg but smpt name is @abc.
com.

Today , I tried to move a test user mailbox (exchange 2000 SP4) from a branch
office to Exchange 2k3 enterprise server using Move Mailbox Wizard from
Exchange 2k3. Both servers are in different domain.
Actually It should be OK. But it show error

"Your organization has at least on Active Directory Connector that is not
Exchange 2003 SP1 or later. Cross administrative groups moves will be blocked
until all Active Directory Connectors have been upgraded to Exchange 2003 SP1
or later."

I checked ADC connector on this server but they haven't installed yet. I
can't check ADC on source server(exchange 2000) as they control to access.
I would to ask some question who had done this process or experience.

1. After ADC installation, what will be potential impact on AD and exchange.
2. Is there any other ways than installing ADC.

Thanks
