This article outlines the complete task flow for migrating mailboxes from GroupWise (version 7.0 and later) to On-Premises Microsoft Exchange, version 2013+.

GroupWise may be running on Windows or Linux.

There are some tools and resources that make the migration easier. Before you start your migration, we suggest you read the following information and linked guides. 

First migration?

We have created a guide to scoping, planning, and managing the migration process. If this is your first migration, we recommend carefully reading this guide.

Exchange questions and troubleshooting

Our Exchange Mailbox FAQ, Exchange Migration Setup and Planning, and Exchange Mailbox Migration Troubleshooting guides contain several common questions and concerns, along with more information, guidance, and steps to resolve issues such as throttling.

MigrationWiz

MigrationWiz is a migration tool, not a syncing tool. If changes are made at the source after migration, they will not sync to the destination, nor will changes made at the destination sync to the source. We do not have “live” monitoring of changes (as with a sync agent) and cannot handle scenarios such as conflict resolution without user interaction.

MigrationWiz supports the capability to share migration projects across a Workgroup. When the Project Sharing feature is turned on, all Agents besides those who are Inactive can view all migrations projects. 

We are not able to support migrations with two-factor or multifactor authentication. 

The maximum individual file size that MigrationWiz can support is 60GB.

Prepare the Source Environment

Enable the SOAP endpoint

Enable the SOAP endpoint on each Post Office Agent (POA).

1. Start GroupWise ConsoleOne.
2. Navigate to GroupWise Agent Settings.
3. Checkmark the Enable SOAP option to enable SOAP access.
4. If the Source environment has multiple POAs, you must open a SOAP port (typically 7191) on each POA.

Generate the User List

This can be generated through your GroupWise ConsoleOne portal. GroupWise migrations require both the email address AND the username, e.g., email address = testuser001@mydomain.com AND username = testuser001.

Credentials

1. Create a Trusted Application Key. This is used to migrate from GroupWise using administrative credentials.
2. Use the GroupWise graphical interface to register a Trusted Application key called "MigrationWiz".
3. Ensure that the application name is set to "MigrationWiz."
4. Make a note of the key value for the application key textbox. This will need to be entered under the Source endpoint in MSPComplete.
5. For GroupWise 8 Support Pack 1 or later, use the graphical user interface tool to register trusted applications.
6. For previous versions, use our command line tool to generate the Trusted Application Key.
   1. Go to the target GroupWise server.
   2. Log in as a GroupWise administrator.
   3. Verify the user has full access to the GroupWise domain folder.
   4. Extract zipped files to a local temporary folder.
   5. Run the EXE with the GroupWise database folder as an argument (ie., GenerateTrustedAppMigrationWizKey.exe C:\Novell\Databases).

Example

• C:\>GenerateTrustedAppMigrationWizKey.exe C:\Novell\Databases
• MigrationWiz Trusted App Key Generator
• Configuring: C:\Novell\Databases
• Key Generated
• Key: 865A15420BA50008B…007BCF0085003000​

If the command does not work, you can use the NETWIN32.DLL command line tool included in the Novel Netware client. If you get the following error: “The program cannot start because NETWIN32.DLL is missing from your computer. Try reinstalling the program to fix this problem” confirm that:

1. The GroupWise client is installed on the computer.
2. The Novell Netware client is installed on the computer.

If these are both installed:

1. Go to a Windows machine.
2. Log in as a GroupWise administrator.
3. Mount a drive letter to the remote target GroupWise server (for example, net use X: \\GW-Server\c$ /u:Administrator).
4. Follow the previously outlined steps using X:\Novell\Databases instead.

Prepare the Destination Environment

1. Set up user accounts.
2. Create an admin account for migration with full access permissions to all mailboxes.
3. Set up a remote PowerShell session with Exchange 2010+.

Grant Access

To manually grant administrative access for migration, execute the following PowerShell command in the Exchange PowerShell Console:
Get-Mailbox -ResultSize Unlimited | Add-MailboxPermission -AccessRights FullAccess -Automapping $false -User MigrationWiz

In the PowerShell script above, change the -User account to match the admin account name for migration.

Any user account that is a part of the domain administrator, schema administrator, or enterprise administrator groups will not have any administrative rights to mailboxes, no matter how many permissions are granted. A security default of the Exchange Server is to deny explicitly any user who is a member of the groups mentioned before. This is why we recommend creating a new user account specific for migration.

Disable Throttling

Disable throttling against the admin account.

To disable all throttling parameters for an admin account called "MigrationWiz":

1. Open the Exchange Management Shell.
2. Type the following command and press Enter.

   New-ThrottlingPolicy MigrationWizPolicy

3. Type the following command and press Enter.

   Set-ThrottlingPolicy MigrationWizPolicy -RCAMaxConcurrency Unlimited -EWSMaxConcurrency Unlimited -EWSMaxSubscriptions Unlimited -CPAMaxConcurrency Unlimited -EwsCutoffBalance Unlimited -EwsMaxBurst Unlimited -EwsRechargeRate Unlimited

4. Type the following command and press Enter.

   Set-Mailbox "MigrationWiz" -ThrottlingPolicy MigrationWizPolicy

Verify Mailbox Accessibility Using EWS

1. Browse to https://login.microsoftonline.com.
2. Log in as an admin email address.
3. Enter the same password as specified in MigrationWiz.
4. Enter the Admin.
5. Click on Users, then Active Users.
6. Search for users entered in MigrationWiz to make sure the admin email address and the end user´s email address specified in MigrationWiz are not misspelled by searching for them.
7. Make sure all users have licenses assigned to them. All mailboxes on the Source system are created as mail users in Office 365. When you assign a license to the mail user, it will become a mailbox user. We need a mailbox at the Destination to be able to migrate data.
8. If you are not using impersonation, make sure the admin account has a license assigned to it. This can even be a temporary trial license.

MigrationWiz Steps

Create a Mailbox Migration project

When there are multiple non-linked Post Office Agents (POAs), you should create multiple Mailbox Migration Projects and match the Source endpoint to the project corresponding to the users on the POA.

1. Click the Go to My Projects button.
2. Click the Create Project button.
3. Click on the type of project that you wish to create. For this migration:

• Mailbox: Mailbox projects are used to migrate the contents of the primary user mailbox from the previous environment to the new environment. Most mailbox migrations can migrate email, calendars, and contacts.

For mailbox migrations, use administrative credentials to access mailboxes. In most migration scenarios, the admin account must have full access rights to the Source mailboxes. 

1. Click Next Step.
2. Enter a Project name and select a Customer.
3. Click Next Step.

Endpoints

Endpoints are now created through MigrationWiz, rather than through MSPComplete. The steps for this section outline how to create the endpoints in MigrationWiz.

If you select an existing endpoint consider only ten endpoints are shown in the drop-down. If you have more than ten, you may need to search. Endpoint search is case and character-specific. For example, Cust0mer will not show up if the search is customer. We recommend keeping a list of endpoints you have created along with any unique spellings or capitalization you may have used.

1. Select a source endpoint or create a new endpoint. To create a new source endpoint:
   1. Click New.
   2. Name the endpoint.
   3. Select type GroupWise 7+
   4. Enter the GroupWise SOAP URL.
   5. Click the Provide Credentials radio button and enter the Trusted Key for the Trusted Application Key that was set up under the "Prepare the Source Environment" section of this guide.
   6. Click Add.
2. Click Next Step.
3. If multiple Post Office Agents (POAs) are not linked, create separate Source endpoints for each POA.
4. Select an existing destination endpoint or create a new destination endpoint. To create a new destination endpoint:
   1. Click New.
   2. Name the endpoint.
   3. Select type Exchange Server 2013+.
   4. Enter the OWA URL.
   5. Click the Provide Credentials radio button, and enter the admin account credentials for the account that was set up under the "Prepare the Destination Environment" section of this guide.
   6. Click Add.
5. Click Next Step.
6. Click Save and Go to Summary.

Add Users

Add user accounts to the project for migration, using various methods depending on project size. Steps for each option are in the accordions below, click to show the option you select and follow the guidance there.

GroupWise migrations require both the email address AND the username, e.g., email address = testuser001@mydomain.com AND username = testuser001.

Small Migrations

Adding users one at a time using Quick Add is a straightforward process for small migrations. 

Larger Migrations

Using the Autodiscover or Bulk Add option you add users for larger migrations.

Advanced Options

The following advanced options show you some options that will help you to perform or complete a migration.

Support Tab

Consider that each Support Option includes the "=" character and must be added under the Support tab in the Support Options section.

Add additional blank fields for new Support Options by clicking on the "+" button. In case you want to delete a field click the trash can icon.

Optional Settings

• FolderMapping=”^Cabinet->Inbox” This option maps folders under the cabinet subfolder on GroupWise, to the Inbox on the Destination.

Performance Tab

• Set Maximum concurrent migrations. We recommend setting this to a low value, such as 10, to ensure that server utilization does not go above 80%. If the Source server has enough server resources, set this parameter based on the bandwidth guideline of three (3) mailboxes per 1Mbps bandwidth. Therefore, for example, if there is a 10Mbps connection, we recommend setting the maximum concurrent migrations parameter to 30. If the Source server has limited available server resources, we recommend setting this value to a lower value to avoid overwhelming the server with requests.
