Exchange enterprise 2003 to exchange sbs 2003

[sillyboy]

Hi, i currently running exchange Enterprise 2003. Because i don't have exchange 2003 enterprise license but only have exchange 2003 sbs, so recently i need to do migration from exchange enterprise 2003 to exchange sbs 2003. But what i concern about is sbs exchange have limitation with their database. I'm not sure whether is it a possible way to doing this so call "downgrade " migration?

Hello,

Thanks for your post.

You cannot simply merge two domains in different organizations with each has Exchange server installed. However, you can join the SBS 2003 domain to an existing domain
and access the previous Exchange server resource as a member server on the network.

Q.
Does the SBS 2003 R2 CAL allow me to access other servers running Exchange Server 2003 or SQL Server 2005 on the network?

A. Yes. If you are running SBS 2003 R2, you are allowed to access any other servers running Windows Server 2003 R2, Exchange Server 2003 Standard or Enterprise
Edition or SQL Server 2005 Workgroup Edition within your SBS 2003 R2 domain.
This is the article you may refer to:

Moreover, as SBS 2003 include Exchange 2003 Standard version which has max 75GB mailbox store, if your Exchange server has small mailboxes, you may also consider
Exmerge tool to achieve you goal.

Hi:

The limits on SBS 2003 in so far as exchange is concerend, are 75 GB total
private store and 75 GB total public store, 75 users or devices.

I suspect if you are in that range you could mount the store if the name
space is the same, but if not you would have to use exmerge, export, or copy
to pst.

You've received a couple of excellent responses from Robbin and Larry.

I am curious how many stores are currently configured, and large are the
combined mailbox databases, as well as the public folder database that is
the currently installed on the Enterprise Edition you current have
installed.

Hi,

Larry's suggestion makes a lot of sense to me. Copy the old database files
to SBS if you are running a single store and are under 75 GB in size. You
will need to have SBS Exchange SP2 and tweak the registry because the default
registry setting is 16 GB.

If you exceed the limit, have you users autoarchive until you get under the
75 GB database size. Aslo, do a backup and maintenance to reduce whitespace
on the exchange DB.

Also, in the registry setting, I would have a max 73 GB, leave yourself a GB
or two in case the store dismounts because you reach the limit, this way you
can increase another GB mount it and start autoarchiving ASAP!

One more point that I don't believe was addressed, is to always allow at
least 110% freespace on the drive where the stores exist. This allows to run
utilities against the database.
