Exchange 5.5 and Exchange 2003 GAL's

We currently have an Exchange 5.5 org running in an old NT 4 domain. We are
in the process of setting up a new AD 2003 domain and Exchange 2003 in mixed
mode but it is a new org and was not joined to the original. What is the
best way to get the GAL replicating between the original 5.5 and the new 2003
exchange? The company was looking into what is it MIIS or MMIS which joins
different Exchange systems and orgs to show one GAL but it appears that will
not happen as soon as our site gets this running so looking at how to do
this.? As always, any insights / help is appreciated!

Regards,
Alan

We get the same situation. We have a central Exchange 5.5/2003 mixed mode
environment, and a remote independent Exchange 5.5 Org in NT 4.0. But worst
still, the two separate Exchange domain bears the same Organization name.
So I can't use ADC to connect the remote Org as Inter-org replication.
According to Microsoft, the only solution is MIIS.

If you don't required synchronizing domain account SIDs, you can use
directory export/import to manually copy the contacts over. However, those
accounts will be shown as contacts only. I have successfully created those
contacts for remote E5.5 users in our central AD.

Mounting an Exchange 2000 store on an Exchange 2003 server Hi all, I already suspect the answer might be *no* because I'm looking for an easy way to migrate from E2K to E2K3, and when it comes to Exchange, nothing is ever easy!!
