I'm working on migrating from Exchange 2003 to GroupWise 7 and will then upgrade to GroupWise 8 using the GroupWise Migration Utility for Microsoft Exchange.

The Exchange server resides in a seperate domain from where GroupWise resides.

In the documentation it states to create 2 DNS records for the Exchange server and the GroupWise domain. Can someone tell me what sort of DNS record it should be and maybe in which DNS zone they mean to create the records (Exchange uses MS DNS and GroupWise has eDirectory DNS, is just an A record suitable for this, will I need to setup delegation within DNS? Any help appreciated with this.
