CCR and Public Folders

Hello,

I 've read multiple articles about CCR and Public Folders that has left me
confused.

My last understanding is that with CCR you can host 1 instance of the Public
Folders with a max of 2 in the organization. I say two because
I believe you can replicate from Exchange 2003 to Exchange 2007 during a
transition.

I happen to have two exchange 2003 servers with 2 copies of Public Folders.
I have also setup Exchange 2007 CCR and while trying to create a new Public
Folder DB on 2007, it fails.

My assumption is that I need to delete one copy of the Public Folders from
Exchange 2003 before I can create a new Public Folder in Exchange 2007 to
replicate.

Does anyone know if this is correct? If not, how do I move my Public Folders
from exchange 2003 to Exchange 2007 with CCR?


Thanks in advance.

See the TechNet article 'Planning for Cluster Continuous Replication" at
http://technet.microsoft.com/en-us/library/bb123996.aspx
Specifically the section "Cluster Continuous Replication and Public Folder
Databases." Hopefully that will clear up some of the confusion.

Technically yes. Once your folders replicate you should remove the original
PF store. See the article link above.

What happens when you try?

The end goal is still the same: to have one PF database on the CCR cluster
and no other PF databases anywhere else in your Exchange Organization. At
some point you will have to remove the replicas from the 2003 servers, but
that shouldn't prevent you from creating a new PF database on the CCR
cluster.

It's the same as what you would do without CCR.

Since you have 2 public folder servers, you won't be allowed to deploy
CCR right off the bat since the first Exchange 2007 server will try to
create a public folder database and you can't have public folder
databases when there's more than 1 public folder database in the
organization. In this case you'd have to bring up a regular mailbox
server first and then you can bring up your CCR. Or you can work on
migrating 1 of the 2003 public folder databases to the other 2003 public
folder database and then remove 1 database while making sure that store
uses the other database as its' default public folder store.

If you decide to just bring up a regular Exchange 2007 mailbox folder to
store public folder information on, you can migrate public folders to
this new Exchange 2007 mailbox server and migrate mailboxes to your CCR.
Then when you decommission Exchange 2003, there will be 1 public
folder database in your environment which will allow you to create the
public folder database on your CCR. You then migrate the data to CCR,
then decommission the regular Exchange 2007 mailbox server.

I found my problem with the PF DB not being able to mount and resolved it
