Understanding Group Migration

A group is the basic unit of work as far as collaboration is concerned. It involves people with common goals, and interests, or people charged with similar responsibilities in an organization so that they can work more efficiently. Whenever you upgrade your groups to Office 365, you are simply transferring these collaborative communities to a cloud-based platform that has several benefits.

Benefits of Migrate On-Premise Distribution Groups to Office 365

That is where the Office 365 groups have a big advantage over the on-premises ones, as the level of integration is significantly higher. In Office 365, groups are deeply integrated with other applications such as Microsoft Teams, SharePoint Online, and Exchange Online. This means it is easy to transfer files, work on the documents, or even make communication within the group more efficient.

There is also flexibility that is attached to Office 365 groups. Another advantage is that the Office 365 groups are flexible in their use. There are a variety of groups that you can create like a security group for controlling access or even a distribution for the mailing list. Also, you can further configure the groups to suit the requirements of a given organization by, integrating the groups with extra properties or even track workflows.

So, before you start the migration of your groups, you will need to familiarize yourself with the current group environment. This includes the identification of accounts for each of the groups, members of the groups, and the data concerning the groups. In this case, such information will assist in developing a more efficient strategy on how to migrate from one organization to the other and the effective realization of the migration process.

What are the Methods to Migrate Groups to Office 365

There are two approaches to elevating Distributed Groups to Office 365 Groups. One involves having an Office 365 global admin or Exchange admin to carry out the upgrade, utilizing either approach.

Using Exchange Admin Center

  • Step 1. First sign in to the Microsoft 365 account using your admin credentials and navigate to the Exchange Server by clicking on the Exchange.

select Exchange to move groups to Office 365

  • Step 2. Choose Recipients and navigate to the Groups

select distribution list from group menu bar

  • Step 3. Then click on the Distribution list option and click on Export.

select the export option

  • Step 4. Next, click on Export Groups to export the specific group members

different options of exporting distribution list

  • Step 5. A small pop-up window shows the estimated time the process takes. Then click on the continue.

tap continue to export

Finally, the process will export the group members from the distribution group to a CSV file.

Using the PowerShell Method

Execute the PowerShell methods using this set of commands to get a proper list to migrate distribution list to Office 365 Powershell.

Run the command mentioned below with Office 365 PowerShell module:

1. $365Logon = Get-Credential
2. $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $365Logon -Authentication Basic -AllowRedirection
3. Import-PSSession $Session

If you want to list the distribution groups, run the cmdlet mentioned below:

Get-DistributionGroup -ResultSize Unlimited

To obtain the list of group members run the cmdlet mentioned below:

Get-DistributionGroupMember -Identity "" -ResultSize Unlimited

Export Group Members From One Distribution List to CSV File

Move Export Group Members Across Multiple Distribution Lists to a CSV Document

1. $DGName = ""
2. Get-DistributionGroupMember -Identity $DGName -ResultSize Unlimited | Select Name, PrimarySMTPAddress, RecipientType |
3. Export-CSV "C:\\Distribution-Group-Members.csv" -NoTypeInformation -Encoding UTF8

Users can interchange the factor with the names of their actual group

Transfer All Distribution Groups As Well As Members to a CSV File

In this approach, initially, users need to retrieve every distribution list by executing the Get-DistributionGroup command. Subsequently, they must extract the list’s members by looping through each group with the Get-DistributionGroupMember PowerShell command.

The command below will save all the groups and their members to a CSV file.

1. $Result=@()

2. $groups = Get-DistributionGroup -ResultSize Unlimited

3. $totalmbx = $groups.Count

4. $i = 1

5. $groups | ForEach-Object {

6. Write-Progress -activity "Processing $_.DisplayName" -status "$i out of $totalmbx completed"

7. $group = $_

8. Get-DistributionGroupMember -Identity $group.Name -ResultSize Unlimited | ForEach-Object {

9. $member = $_

10. $Result += New-Object PSObject -property @{

11. GroupName = $group.DisplayName

12. Member = $member.Name

13. EmailAddress = $member.PrimarySMTPAddress

14. RecipientType= $member.RecipientType

15. }}

16. $i++

17. }

18. $Result | Export-CSV "C:\\All-Distribution-Group-Members.csv" -NoTypeInformation -Encoding UTF8

What are the Factors to Consider When You Migrate Groups to Office 365

Currently, the only way to migrate distribution list to exchange online Groups is through a specific process. This means that a Distribution Group, initially set up and maintained on-site Exchange, cannot be directly converted to an Office 365 Group. There are additional limitations on lists as well.

Factors to Consider When You Migrate Groups to Office 365

Dynamic Distribution lists and security groups are not eligible for this transfer. Furthermore, Distribution Lists that either need an owner or have more than 100 owners are not eligible for an upgrade. However, it is feasible to determine if a Distribution List meets the criteria for an upgrade by employing a PowerShell script.
