How to export "Managed by" field of Distribution and Security groups and import with new values? (Exchange 2010, AD 2003)

Question

My Active Directory environment is 2003 functional level and we have Exchange 2010.
I am trying to find out the best way to do a mass edit for the "Managed by" values of our security and distribution groups.
I know we can export the "managed by" field by csvde but I am not sure this is the correct way to do it. Also in the case that there are multiple users assigned to be managing a distribution group it only shows one value. Also powershell from Exchange
2010 can be used with "get-distribution" but as our AD environment is 2003 is this correct also?
Finally once the data is exported to csv can it be edited to then reimport and udpate the existing group managed by fields with new values?
Not really sure that the best way to go about this is.
Summary - We have 2003 AD with Exchange 2010 and I am trying to export a list of all our Distribution/Security groups showing the group name and managedby values so we can edit and update the
existing managedby values with new ones. In some cases we have multiple users as the owners.
Appreciate any advice on how this can be best achieved. Thank you.

Hi,
We can use the following command in Exchange 2010 to export "Managed by" field of Distribution and Security groups:
Get-DistributionGroup | Select-object Name,@{label="ManagedBy";expression={[string]::join(“;”,$_.managedby)}},Primarysmtpaddress | Export-Csv
C:\export.csv
After you changed the Managed by field in export.csv and saved it as a new file named import.csv, we can run the following command to set with new value:
Import-Csv C:\import.csv | Foreach-Object{ Set-DistributionGroup –Identity $_.Name –ManagedBy $_.ManagedBy}
Hope it works.
