Upgrade Custom Recipient Policies as part of Exchange 2003 to 2010 Migration

Hello,

We have Exchange 2003 and Exchange 2010 in co-existence. I have migrated all Mailboxes to Exchange 2010. Now I want to upgrade Recipient Policies.

We have 1 Default Policy, which I know how to upgrade

Set-EmailAddressPolicy "Default Policy" -IncludedRecipients AllReipients.

But my I dont know how to do it for 2 other Custom Policies. I came to know about the conversion scripts (http://technet.microsoft.com/en-us/library/dd351283.aspx) but not sure how to run. I mean simply run the script on Exchange 2010 server or any special parameters needs to be included.

I can let you know the custom policies if required.

Thanks,

Mihir
