Moving Public folders from one Exchange 2007 server to another 2007 server

Hi,

I will be moving all public folders to a new server and decommissioning the old one. I have a process worked out that moves the public folders using the Moveallreplicas.ps1 script. I confirmed that it works in my lab, it creates the folder hierarchy on the new server, moves all content, and then removes all content from the original public folders. I can then delete the public folders on the old server and all is good.
Almost. I noticed that all of my mail-enabled public folders are no longer mail enabled in the new database. Not a problem for my test environment, but in production where we have many mail enabled folders, and I would not want to have to manually copy and reapply those settings. Is there a way that I can move all public folders and ensure all settings (ie, mail-enable,  folder permissions, etc) are carried over in the move?  
Also, at which point would you recommend I start pointing the mailbox databases to the new public folders? Since it looks like the whole process might take up to a week or longer, I'm concerned that if I point them too soon, the new folders will not have all their content updated, and of course if I wait too long then they will be pointing to folders that have had their content deleted. Or is their a referral list in which I can point to more than one during the move?
I've still yet to find a comprehensive How-to that takes into consideration all the steps involved moving public folders.

Thanks,

Max
