Hi experts,

I currently have two exchange server 2003 and 2010 with more than 300 distribution groups.
I want to keep all distribution groups on 2010. Is there any PowerShell command which can tell me which group is hosted where?

I can see all group in 2010 but not 2003 but before I shutdown 2003 I want to make sure no group left on 2003.
Is there any precision I need to aware of before moving from exchange 2003 to 2010?

Thank you

It's not necessary to do anything, but once you modify a distribution list using the Exchange 2010 management tools (for the first time) it will prompt you about upgrading the version of the object. Once it's upgraded you should not modify the properties of the group using the old Ex2003 tools.

Like I said, it's not strictly necessary. Once you decomission Exchange 2003 it won't even matter anymore.
If you want to force the upgrade of the objects version, run the following command in the Exchange Management Shell:
Get-DistributionGroup | Set-DistributionGroup
