Groupwise to Excahnge Migration

Hello:

I am doing a Groupwise 6 to Exchange 2003 migration of about 35
mailboxes.  The Gateway is working and I can send mail to both systems
fine.  I did a test migration and it worked great.

We will be retiring groupwise after the migration is over.  The
question is what is the next step to get the Internet mail working for
the Exchange side.

I know I will need to tell the Exchange server to accept mail for
@groupwise_domain.com in recipient policy, and then the smtp addresses
will be generated for this domain.

The question is, if I move the MX record to the Exchange server and
accept mail for @groupwise_domain.com will the mail get to the
groupwise users have not been migrated?

For the test user I migrated he now has two entries int he Groupwise
address book, one for the original and one for Exchange.

Thanks in advance for the answer.

Mark

Nope. I think you will probably want to migrate them all at once. It's only
35 mailboxes - shouldn't be that big a deal, no?

Are the users accessing GW through Outlook already?

Well it took about an hour to migrate one medium size mailblox.
Probably will be a weekend project.

No but on the first phase of the migration the AD users were created.

Yes, it should be, definitely! But an hour for a mailbox sounds like a lot.
How big is the mailbox? What network speed? etc.

If you want to do this in stages, flip the mail delivery to Exchange, and
have the "unmigrated" users access their Exchange mailboxes via OWA while
keeping GW open for older items.

You can access GW in Outlook, you know. At least you used to be able to. I
haven't used GW for a while.
