This guide is dedicated to the new Cloudiway migration product. If you wish to use this new version, please contact us.
Cloudiway’s Teams migration solution helps businesses perform technical migrations through a simple SaaS interface. As a result, Teams migrations require no additional software installation or overhead, and migrations can be performed securely and quickly.
This guide is aimed at experienced system administrators who are capable of connecting to remote systems and using a variety of administration tools.
The Cloudiway Platform allows migrating the Microsoft Teams and the Office 365 unified Groups.
1.1. Performance & Security
For more information about security, please refer to this article.
For more information about migration performance, please refer to this article.
1.2. License Management
Cloudiway platform automatically assigns the licenses, for more details regarding the license management, check out this page.
1.3. Delta Passes
Delta migration is a Cloudiway functionality that allows you to migrate incrementally. Changes are migrated during delta passes. Deletions are not propagated.
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, contact us. This will ensure a fast, cost-effective, and stress-free implementation.
2.1. How it works
Migration uses a mix of Graph APIs and CSOM calls. Therefore it requires to configure specific permissions at the source and at the target to execute Graph and CSOM calls.
2.2. Mapping Table
In Microsoft Teams, there are permissions and metadata (createdby, modifiedby, etc.) that contain email addresses. During the migration, these addresses must be converted into target accounts.
To achieve this, Cloudiway uses a mapping table to perform the conversion.
Important: the mapping table must be exhaustive, any missing email address will not be converted, and would end up with the loss of permissions and metadata.
Prepare your mapping table for users and groups/teams in CSV format, ready to upload later on.
2.3. Source Prerequisites
First, we recommend to create an account dedicated to the migration, that can be deleted once the migration is completed.
2.4. Target Prerequisites
We recommend to create an account dedicated to the migration, that can be deleted once the migration is completed.
Cloudiway automatically creates the team, therefore it doesn’t have to exist prior to the migration. If it already exists, it will be used and data appended to it.
2.5. Azure Active Directory Application
Graph APIs calls are performed through an Azure Active Directory Application which is granted specific permissions.
You can either create an Azure Active Directory Application manually or let the platform create one for you.
Please consult our How To Create Azure Apps Registration page to create the Azure Active Directory Application and associated permissions.
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. You will need to set up a connector for each source tenant and each target tenant. Please refer to this page to configure your connectors.
For large projects, it’s possible to create multiple connectors that will be used in parallel. Please contact Cloudiway consulting services if you need to set up such configuration.
Note: to test the migration, you can use a Trial License, please consult this article to assign a Trial License.
To perform the Group migration, navigate to Sites > Group List
You have 3 different methods to fill the list:
4.1.1. Option 1: Get List
The Get List entry under the MIGRATION menu connects to the source and retrieves the full list of teams and unified groups.
This is a useful tool which provides you with a complete picture of groups and teams to be migrated.
Select the connector you want to connect, click on GET.
Note: you can monitor the progress of this task in the Global Logs.
Once the job is completed, the list displays all the teams. Next, you need to assign a target connector to all the entries.
Select the entries, click on MANAGE, then Assign Target.
Select the connector, click on Assign.
Note: if your discovery has found unified groups, you can either migrate to unified groups or Microsoft Teams. You can change the target with the option MANAGE, Change Target Recipient, and select unified groups or teams.
4.1.2. Option 2: CSV import
If you have a CSV file of all your teams, you can upload the file to Cloudiway.
The file must have the following fields in the header row:
|SourceName||The team name|
|SourceId||The relative URL of the team|
|SourceEmailAddress||The source email address of the team|
|TargetName||The target name of the team|
|TargetChannelName||Not used, leave blank|
|TargetEmailAddress||The target email address of the team|
|TargetUrl||Not used, automatically generated by SharePoint|
|TemplateName||Not used, leave blank|
|Description||Short description of the team (without special characters)|
Click on MANAGE, Import, select the CSV File, the Source and Target Connectors, then click Upload.
4.1.3. Option 3: Create an entry manually
Many of our first-time customers create a single team for testing purposes.
Click on MANAGE, Create.
Click on OK.
Click on Mapping Table.
You can upload a User or Group list via CSV (use IMPORT) or CREATE your entries manually.
A template of CSV file is available on the platform when you click on IMPORT.
EntryType: enter 0 for user, 1 for group.
FirstName and LastName: Leave blank for group.
At this point, you are ready to migrate.
You can review the settings in Global Settings.
|Membership Migration||Enable the migration of team members|
|Conversation Migration||Enable the migration of channel Conversations|
|Planner Migration||Enable the migration of Planners|
|Mailbox Migration||Enable the migration of team mailboxes|
