4. Microsoft Teams Migration Scope
4.1 What can be migrated?
When migrating Teams between Office 365 tenants, the following site items can be migrated:
Teams are recreated.
The associated SharePoint Modern Site is created.
The flag Public / Private is migrated.
Owners and Members are migrated.
The SharePoint Site is migrated.
The associated mailbox is migrated.
Channels (for Teams) are recreated.
Conversations are migrated (including @Mentions)
Planners are migrated (tabs, plans, buckets, and tasks including start date, due date, assignees, status, checklist and references).
Files are migrated.
Metadata (date of creation, modification, creator, modified by on files and site items are migrated).
OneNote tabs are migrated.
4.2. Migration limitations
MetaData on conversations are not migrated (Sender, DateTime of the chat message).
Delta migration is a Cloudiway functionality that allows you to migrate incrementally. Changes are migrated during delta passes. Deletions are not propagated.
This guide is aimed at experienced system administrators who are capable of connecting to remote systems and using a variety of administration tools.
Although we provide support for our own products, we do not provide support for third-party products such as PowerShell or server administration of Microsoft products.
If you are concerned you might have any difficulty completing these steps, please consider a solution with our consulting team, contactable via firstname.lastname@example.org. This will ensure a fast, cost-effective and stress-free implementation.
5. Pre-migration configuration
5.1 Before you start
Before you start, you will need to ensure you have the details outlined in the following table.
Stores details and provides communication between the systems you already use.
Office 365 account with admin role for migration at target
An account with admin role that bypasses SSO and is able to authenticate using username/password credentials, preferably with the format: email@example.com. Used for migration of permissions only.
We recommend you create an account with admin access, especially for migration. After all, migrations are complete, simply delete this admin account.
For CSOM access, the migration account must be SharePoint administrator.
To perform the migration, the migration account needs to be an Owner and a Member of the Group/Team, in the source and in the target. If your source migration account is not Owner and Member of the Team, the migration engine will add it automatically. For that, we need the Group.ReadWriteAll in the Source as well as the Target.
The migration account must have a valid license that allows it to access to the mailbox and to Teams.
6. Use The Cloudiway Platform To Migrate Your Microsoft Teams
6.1. Create your source connector
To facilitate the Teams migration, the Cloudiway platform needs to be able to communicate with both your source and target domains. To do this, Cloudiway uses connectors, which are configured on apps.cloudiway.com. You will need to set up a connector for each source tenant and each target tenant. Follow the steps below to configure a source connector.
You can choose to manually set up your connectors, or you can use the simpler process of the wizard. The steps below will walk you through the manual process.
Click on Sources, then on the + New option at the bottom of the screen
Click on Office Group / Teams and type a meaningful name in Connector name
Click on the Create button
Fill in the remaining details
Name of the tenant: enter the name of your tenant (ie cloudiwaylab), not cloudiwaylab.com or cloudiwaylab.sharepoint.comFilling this field automatically fills the URL field. Server Region: Most of the time, keep the default value “Worldwide” except if you have a China, German or US Governmental tenant. Domain Name: Enter the name of your primary domain. Migration User: A SharePoint administrator account ( for permissions to run CSOM calls). User Password: The password of the migration user. This is stored encrypted in EAS 256. Client ID / Client Secret: Graph API client ID and secrets with permissions to access, groups, users and sites. See this article for creating the application: https://kb.cloudiway.com/article/azure-apps-registration/
Click on the save button and jump to the next section
6.2. Create your target connector
With the source connector now configured on the Cloudiway platform, it’s time to create and configure the target connector. Follow the steps below to configure an Office 365 Group / Team target connector.
Click on Targets on the left, then + New on the Action bar at the bottom of the screen.
Click on Office Groups / Teams Online and type a meaningful name in Connector name.
Click on the Create button.
Fill in the fields.
Server Region: Most of the time, keep the default value “Worldwide” except if you have a China, German or US Governmental tenant. Name of the tenant: enter the name of your tenant (ie cloudiwaylab), not cloudiwaylab.com or cloudiwaylab.sharepoint.com. Filling this field automatically fills the URL field. Domain Name: Enter the name of your primary domain. Migration User: A SharePoint administrator account ( for permissions to run CSOM calls). User Password: The password of the migration user. This is stored encrypted in EAS 256. Client ID / Client Secret: Graph API client ID and secrets with permissions to access, groups, users and sites. See this article for creating the application: https://kb.cloudiway.com/article/azure-apps-registration/
Click on the Save button at the bottom of the screen.
6.3. Discover Teams
The Cloudiway platform provides a tool called Get Groups / Teams which returns a list of all groups and teams from the domain you added to the source connector. This is a useful tool which provides you with a complete picture of groups and teams to be migrated.
You should therefore run this tool prior to group/teams.
Navigate to menu Site & Group Migration / Group List
In the bottom Bar, select Migration / Get Groups / Teams
Select your source from the dropdown list and click on the Get button
The tool will schedule a call to your domain to return a list of all visible Groups and sites for migration.
Once the Get Groups / Teams tool has completed, it will return a list of all groups and teams discovered via the source connector’s credentials. The list will appear in the Group List area of the Cloudiway platform.
From this list, you can check what is due to be migrated prior to migration, edit the group definitions, assign licenses and delete any group or team that don’t need to be migrated. These actions are explained in the following sections.
You can also download the results in CSV format for your own records or to make editing changes, and then upload the updated CSV file to the Cloudiway platform as your final list to be migrated.
Note: you cannot add new entries to the CSV file: they must exist on the Cloudiway platform already. If you need to add a new group or team, either re-run the Get Sites (which will add newly-available sites to the existing list) or add a group or team manually using the steps in section 6.6.
6.4. Add target connector
From the group list, select the groups and teams of your choice and click on Manage / Assign Targets.
Select your target from the dropdown list and click on the Assign button.
6.5. Assign licenses
In the same way you assigned the targets, now assign the licenses.
From the group list, select the groups and teams of your choice and click on Manage / Assign Licenses.
You can manually edit the details of the group or team.
For this, click on the line to edit it.
6.6. Manually create an entry in the list
Due to the possibility of typos, we recommend you only use this option if it’s impossible to rerun the Get Groups command.
Ensure you’re still in the Site & Group Migration area of apps.cloudiway.com and go to Group List.
Click on Manage / Create Single.
Fill in the fields
Source name: Name of the Group or Team.Source: Select the source connector.Source URL: Enter the relative URL of the SharePoint modern Site.Source Email Address: Enter the email address of the group or team.Target Name: Enter the name of the group in the target.Target: Select the target connector.Target Recipient Type: select the type of target object: This can be a group, a shared mailbox or a team.License: Assign a license.
Click on the Create button.
6.7. Import or create a mapping table of users and group details
In order to migrate permissions and metadata (createdby, modifiedby, etc…), a mapping table of users must be defined.
A list of mail users is used as mapping tables as it defines who has access to the different sites. It is also used to migrate metadata for files and folders.
You can upload a user or group list via CSV, use Cloudiway’s automated Import Users tool, or manually add each user on the Cloudiway platform.
6.7.1. Option 1: CSV import
If you have a CSV file of all your site users and another one for groups, you can upload the files to Cloudiway. The files must have the following fields in the header row:
User CSV: FirstName;LastName;SourceEmail;TargetEmail
Group CSV: Name;SourceEmail;TargetEmail
If you perform more than one upload, any CSV data already uploaded will not be overwritten by the following uploads. Therefore, duplicates can occur. Sample CSV files are available to download during the steps below.
From the Site Migration area of apps.cloudiway.com and go to Mapping Tables.
Click on Manage on the action bar and select Upload CSV.
If required, click on Download sample CSV and add your users to the CSV file using the sample headers (FirstName;LastName;SourceEmail;TargetEmail)
When you have a complete CSV file with the correct headers, click on the Upload button.
Locate your CSV file within your own file system, and double-click on it to select it. If the CSV file format is not correct, you will see an error message on your screen:
If you see any error messages, check your CSV file to ensure it has four columns each with a separator (including the last), and try uploading again.
Once the CSV file format is correct, you will see a confirmation message at the top of your screen:
To upload a group CSV, click on the Groups tab in the top right corner and repeat steps 2 to 6.
Check your email for confirmation that all uploads have been completed: you can also refresh the Cloudiway platform to display your imported users at any time.
If you wish to edit any user or group that’s been uploaded, click on their name from the user list or group list to display the editable list of fields.
6.7.2. Option 2: Create a single user or group
Many of our first-time customers create a single user and/or group for testing purposes. This provides a means of watching the migration process without affecting all users. Single users and groups can also be created for migrations affecting just a few users.
Go to the Mapping Tables area of the Site & Group Migration menu
Click on Manage on the action bar at the bottom of the screen and select Create Single to display the following screen:
Fill in all details for a new user
Click on the Create button The new user will be added to the Site Migration / Mapping Tables screen:
Repeat steps 1 to 4 for any more users you’d like to create.
If you’d like to manually add a group, click on Groups in the top left corner of the screen, then repeat steps 2 to 5.
Cloudiway provides a preprocessing tool that will set automatically all the required permissions at the source and at the target and provision the groups and teams at the target.
What does the preprocessing tool?
At the source:
It uses the graph APIS (Client ID and Client Secret) to give the migration account defined in the source connector the owner Role. This ensures that the migration account will have all the necessary permissions during the migration.
At the target:
It creates the group or Team and the associated SharePoint modern site under the context of the migration account defined in the target connector.
It sets the permissions to the migration account if the target group or team already existed
It sets all the members and owners to the group.
It creates the additional SharePoint libraries that may have been manually created.
At the end of the preprocessing, the status of the migration is set to “Not Started”. The group or team is now ready to be migrated.
How to run the preprocessing?
Ensure you’re still in the Site & Group Migration area of apps.cloudiway.com and go to Group List.
Select the groups or teams you would like to start preprocessing by clicking on their individual checkbox, or by selecting all groups and teams with the checkbox at the top of the list.
Click on Migration in the bottom left corner of the action bar and select Pre-Processing to begin the process.
Click on the Site Data tab to see a list of what can be found in the site.
Click on one of the plus signs to see further information about the page and its site content.
With this level of detail about pages and contents, you can verify any troublesome items unlikely to be migrated prior to starting migration. You should also use the audit to cross-check any missing items from the audit that are present on your source site.
6.9. Activate and monitor your migration
Now that you have performed all the pre-migration steps within your tenants and within Cloudiway, you’re ready to migrate. We recommend you run a test migration on a single site first to check that your configuration produces the outcome you expect.
To start your migration, select the Group or Team you wish to migrate and click on the Start button. Your batch will be scheduled and will begin as soon as resources are available.
