looking for powershell/exchange (2007) ems scripts to help extract data from exchange 2007 accounts

Hi All:

I have two companies that are merging -

I need to migrate an exchange 2007 user base from one domain (where it is a DC) to another domain's exchange 2010 server (which is a member server).I'm looking for some power shell scripts, that may help me extract data from the source exchange 2007 server which includes for each account:

1) Aliases
2) groups belonged to
3) delegates

And then maybe some scripts to import that same data into the new accounts in the exchange 2010 environment.

Thanks in advance for any tips or direction.

What do you mean by Aliases? Are you looking for email addresses of mailbox?
Firstly are these two domains on the same site? Can you not use the standard domain migration tools and processes for moving users accross domains/forests?

They are not on the same site.  They are separate physical locations.

Yes, by aliases I mean email aliases, as many of the mailboxes could contain ten or more aliases. A bigger issue is the delegates though.
To export the Email Addresses..
Get-Mailbox -ResultSize Unlimited | select name,{$_.EmailAddresses} | Export-Csv C:\report.csv -NoTypeInformation

Open in new window


To export the Delegates (Only Delegates will be listed not calendar permissions)..
Get-mailboxcalendarsettings -ResultSize Unlimited | select name,{$_.ResourceDelegates} | Export-Csv C:\ResourceDelegates.csv -NoTypeInformation

Open in new window


For group membership, are you looking to get only distribution groups?
Subsun, yes thats what I am looking for. Does the first one also list the mailboxe's aliases ?

And yes, just distribution group information....

THANK YOU !
