Upgrade Distribution Group to Exchange 2010 Version

Hi Readers,

We have found that there are many DL’s in our organization that are still on old versions.

How to find DL versions:-

Log on to exchange 2010 management shell:

$collect = Get-DistributionGroup -ResultSize unmilited | select Name,samaccountname,exchangeversion

$collect | export-csv c:\exportDl.csv

Now you have two options to upgrade

1. upgrade all Lists at ones

Get-DistributionGroup -ResultSize unlimited | Set-DistributionGroup -forceupgrade

2.  Do some of the lists to see how it goes like I have done only 250 to first check

Set-DistributionGroup “DLName”  -forceupgrade

you can use notepad++ & you don’t have to write any script, follow below screen shot.

step1: replace ^(.+)$ with “\1″ (Regular expression should be selected at below)




step3: After replace it will look like below


Now enter these in Shell :)
