Can not edit mail non-universal group

Question

Hi all,
After moving from Exchange 2003 to Exchange 2010, the previous distribution groups become mail non-universal groups and greyed out.  i can not edit them anymore.
Some DGs contains some distribution groups or secutiry groups.
I can not create  nested distribution groups anymore in Exchange 2010.
How can I make them not greyout and I am ble to edit them?
Thank you.

Ok.
So I’d use the code above and run it a couple of times, just it will error groups with group membership but the first pass will change the scope of the child group and the second should change the scope of the parent group. This is a lazy approach
but I want to get you the code to create the DG’s ;o)
Once you have your groups at Universal level you can make DG’s
I use the code below to batch create DG's with prefixed names or email addresses
Import-Module ActiveDirectory
Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010
Connect-ExchangeServer -auto
$GroupsWithOutEmails = @(Get-ADGroup -Filter {(mail -notlike "*")} -SearchBase 'OU=Staff,OU=Groups,OU=Live,DC=domain,DC=co,DC=uk' -Properties mail )
ForEach ($GroupsWithOutEmail in $GroupsWithOutEmails){
$Alias = $GroupsWithOutEmail.Name.Replace(" ","")
$SimpleName = $Alias.Replace("_","")
$Identity = $GroupsWithOutEmail.DistinguishedName
$PrettyName = "StaffGroup - All " + $GroupsWithOutEmail.Name + " Staff"
$PrettyeMailAddress = "SMTP:StaffGroup_" + $Alias + "@domain.co.uk"
Write-Host $Alias $Identity $PrettyName $PrettyeMailAddress
Enable-DistributionGroup -Identity $Identity -Alias $Alias
Set-DistributionGroup -Identity $Identity -DisplayName $PrettyName -EmailAddressPolicyEnabled $false -EmailAddresses $PrettyeMailAddress -SimpleDisplayName $SimpleName
There's some code in there to get around some of our groups which had "_" in them and Exchange didn't like. If you just want enalbe the groups as DG's then remove the "Set-DistributionGroup" line
Is that any help?
