Free/Busy and Public folder movement - Exchange 2003 to 2010 transition

Hello,

We are transitioning Exchange 2003 to 2010.

I have installed Exchange 2010 CAS and Mailbox roles.

I also got warning;

If Microsoft Outlook 2003 is in use, you should replicate the free/busy folder on this server to every other free/busy server in the organisation."

I will not be changing smarthost from 2003 to 2010 right now.

After 1 week we are going to move Public Folders and Mailboxes.

My question is;

1) Is it compulsory to move Free/Busy and Public folder after exchange installation?

OR

2) Since currently all user's mailboxes are on 2003, I can perform this FREE/BUSY and Public folder movement after 1 week when moving mailboxes also?

Thanks,

Mihir

So existing users on Exchange 2003 will not be having any impact in terms of accessing Public Folders and Free/busy information till we move Public Folders and free-busy information after 1 week of Exchange installation?

I had referred this article, but wanted to confirm as we are not doing complete transition in a single day. After a week or so will be moving PF and mailboxes.

thanks.

Hi,
before "moving" the public folders (and system folders) you must replicate them to at least one exchange 2010 server.
All PF replica should be synchronized before moving your mailboxes so that migrated mailboxes could access 2010 PF up to date replica (Default accessed PF is set at the database level)

The last step is the effective move of the public folders which results in a last sync and the deletion of 2003 replica.

You may use predefined powershell scripts for each operation, see the link below

If you have problems migrating the Public Folders using the MS migration toold, follow the instructions accepted as the Answer - HERE to do it manually. That Post/Answer is for 2003-2007 migration but it is also sometimes needed for 2003-2007-2010-2013 migrations.

This was the only way I could get them into Exchange 2010 from 2003 - it was also the only way numerous others could migrate them as well.
