Introduction to
Public Folder Migration
When you administer Exchange, Public folders always seem to have their own
personality separate from the mailboxes. It is the same for migration,
Public Folders need their own plan to replicate and move data from Exchange 5.5.
Topics for Public Folder Migration
The key question is will you have a dedicated public folder server, or
whether to run the mail and public folder on the same Exchange 2003 machine?
The answer depends on the size of your organization. For large
companies separating public folder traffic from mailbox traffic is
essential, while on small organization co-existence would be more cost
effective.
Another consideration is how many public folders servers do you need?
One for each of the main sites would be a good starting point. Clients
at small sites could access public folders on the larger sites provided the
network was fast enough.
Exchange 2003 has a new tool called pfMigrate that helps you to migrate
both system folders and public folders from Exchange 5.5. The key
concept is Replica. You can use pfMigrate to create replica folders on
the new server. Unlike Exchange 5.5, you do not need to set a home
server for a public folder in Exchange Server 2003. This is because
Active Directory uses the multiple master model whereby any server has a
read write copy of the public folder information.
With pfMigrate you can carry out a trial run and produce a report; if you
like what you see then you can run the tool again and actually migrate the
public folders.
pfMigrate.wsf is actually a command-line script rather than an executable. You will find the
script on the ExchangeCD\Support\ExDeploy folder. Alternatively, you can
run the script through the Exchange Deployment Tools which you find on the first
screen of the setup menu.
Trap:
After you run pfMigrate, only the hierarchy of the system folders and
public folders is migrated immediately. Be patient and wait for replication
for the actual contents of the folders to be migrated.
You can use the Active Directory Connector to create agreements to
synchronize and migrate public folders from Exchange 5.5 to Exchange 2003.
These are the same principles that you used to make ADC agreements for
mailboxes.
Exchange Server 2007 is a complex topic, do you need practical hands on training? As an MCT trainer, I can thoroughly recommend
TrainSignal. In particular, I like the way
that TrainSignal cover all learning methods, instructor lead, video and of course text
material. You can either take one module, for example Exchange 2007 or go for a combination of modules.
