Hi Michael:
The customer I'm supporting directly currently has an Exchange
2003 environment. This environment is in the process of being upgraded to
Exchange 2010. The servers aren't installed yet, but soon will be and will
be part of the existing Exchange 2003 organization. Eventually all the
mailboxes from the customer's Exchange organization will be moved into the
Exchange 2010 servers.
The customer has completed the takeover of several external
companies. These outside companies are also running Exchange. The customer
wants me to perform a Cross Forest merge/migration from the Exchange
environments in these external companies, into their soon to be up and
running Exchange 2010 environment.
I have GALSYNC and Schedule+ Free/Busy up and running to provide
coexistence between the customer and one acquisition that's running Exchange
2007. I would like to keep this up to support the other coexistence partners
(as they come along) since the process is fairly simple, and stable.
At the moment, I'm looking for pointers to documents that can
provide me clear explanations on how to do that.
Hope that clears up the confusion.
John M.

Who is doing 2007 to 2010?
Who is doing 2003 to 2007
I am confused.

Subject: Cross Forest Migration from Exchange 2007 to Exchange 2010
Good morning all:
I'm assigned to a customer that has acquired another company. I've
been tasked with coming up with a migration plan to accomplish the
migration.
The current environment is Exchange 2003, but the customer's base
environment is being upgraded to Exchange 2010 in the near future. All of
the migrations are going to be onto Exchange 2010 servers.
I've been through TechNet, well have gotten lost in the various
articles, blogs, social stuff, trying to find a decent article that is
rather straightforward on setting up a migration from 2007 to 2010.
Coexistence is already set up. GAL SYNC and Schedule+ Free/Busy are running
into the customer's Exchange 2003 environment already and is stable. I'd
like to keep that up, since it's already there. But if it needs to move, I
can probably do that.
Does anyone have pointers to good, informative articles on the Cross
Forest Migration process?
Thanks.
John M.
