Are you taking on
the task of migrating your enterprise Exchange server to Exchange 2000?
Or are you doing research before the deployment? You would probably want
to grab as much reference as possible before this monstrous task. These
are several items to consider:
Site
Setup -
Is your Exchange 2000 computer installed into the same site that your
Exchange 5.5 server and its mailboxes are? This will make the job so much
easier, not to mention with the increased capacity of Exchange 2000, you
can now combine your Exchange 5.5 farm into fewer Exchange 2000 servers.
Back
up - Exchange
administrators know that online backup is THE way to back up an Exchange
server. Before your migration, be sure to perform an online backup using
downlevel software of the information stores (IS) and Directory (DS) of
your current servers just like your usual backup. If you use both private
and public information stores, then priv.edb and pub.edb are to be backed
up as well. Next is to back up your Exchange 2000 server (destination).
To save time, you can just back up storage groups in which you will be
migrating mailboxes into.
Moving
Mailboxes - Exchange 2000 has a task wizard that will make
your job easier. Once you identify which domain your Exchange 5.5 and
its user accounts are, select 1 or any number of mailboxes, select which
Exchange 2000 server to move to, then you may go have a cup of coffee
while watching them move.
Another
Back Up - What? Another one? This ensures that you have a snapshot
of the server right after migration, in case you need to roll back to
this point after the next step.
Moving
Public Folder - This is not as easy as moving mailboxes, but
there's also a tool to help you. You will need to do a replication of
the public folder, which can be done using the Exchange 5.5 Administrator
tool or the Exchange 2000 Manager tool.
To do it within Exchange
5.5, fire up the Administrator tool and expand the organization
tree in the left pane. Expand Folders and then Public Folders.
Select the folder you want to replicate and from the File menu,
choose Properties. Select the replicas tab in the property page.
From the Servers list, choose the server that you want to create
the replica in, click Add and then OK. When completed, go back to Properties
again and this time on the Advanced tab, choose the server that
has the replica of the public folder, hit OK. A Performing Directory
Replication dialog box will pop up and tell you that the directory
is being changed and once completed, your Exchange 5.5 DS is updated with
the Home Server information. Verify by pulling up the Properties
page of the public folder and checking under Folder Replication Status,
all replicas should be shown as in sync. <Note that the replication
will take some time and you should only do this when you are certain that
your Exchange 5.5 server is not to be used as a production box anymore>
To do it in Exchange
2000, fire up the System Manager and browse within
the Administrative Groups, within the name of your site,
you should find the public folders that you want to move, select the folder
for replication. From the Action menu, click Properties
and choose the Replication tab. Click Add to see a list
of destination servers containing public folder databases. Choose your
destination server and OK. In the Replication message priority
field, remember to set it to Urgent, so you can be sure that the
folder is updated once data is received. OK again and replication is in
progress.
Backing
up yet again
- Yes, one more time as this concludes the migration of your Exchange
servers. Next will be some more testing, wiping off the sweat off your
forehead, be it cold sweat or not, and announce your success to the everyone
list.
