Populating Collections

You can populate any existing collection using a comma-separated values (CSV) file with team attributes.

NOTES:
  • CSV file can contain one or more columns. There are no special requirements for header names.
  • One of column must contain case sensitive mail nickname data that will be used for matching.
  • File names with non-ASCII characters are not supported.

To populate collection from CSV file

  1. Prepare a comma-separated values (CSV) file with data of discovered teams you want to add to the collection. File can contain teams that have not been discovered, but these teams won't be added to the collection. One of the columns should contain the mail nicknames. For example:

mailNickname, ...

SampleName,...

  1. Select a collection you want to populate on Dashboard and click it to open the Collection Dashboard.
  2. Click Fill from File to populate the collection with discovered objects you specified in the file created on Step 1.
  3. Click Browse to open the comma-separated CSV file created on Step 1.
  4. Browse for file and click Open. Selected file name appears next to the Browse button.
  1. Click Populate to populate the collection.

The collection is populated. You can see added objects on the Collection Dashboard.

NOTE: The objects that do not exist in the source and/or target tenants and the source teams that are not enumerated during the Discovery are ignored without producing an event.

Exporting Mapping for Teams

To export the teams mapping as a comma-separated values (CSV) file, select the required teams on the Teams tab on Teams migration Dashboard and click Export.

You can customize this file and use it as a base for manual mapping.

Exported data will contain source team name (may be team IDisntead), suggested target team name to provision and MailNickName MailNickName parameter specifies the alias for the associated Office 365 Group. This value will be used for the mail enabled object and will be used as PrimarySmtpAddress for this Office 365 Group. The value of the MailNickName parameter has to be unique across your tenant.

Using Manual Mapping for Teams

In some cases, you might want to rename the teams on target or merge them with the existing teams with different names. To achieve this goal, provide a file with the custom mapping between source and target teams. You might use the exported team mapping as a template.

  1. Export a comma-separated values (CSV) as described in Exporting Mapping for Teams. Alternatively, you can create and use your own CSV file, as described below.
  2. Edit Target Team Name column only to specify the target team names to create desired matched pairs. Do not change the rest of columns.

Important: When editing a CSV file, the following should be considered:

  • To ensure manual mapping will be completed successfully do not remove any columns from exported csv file.
  • You can edit Target Team Name entries only, if necessary. Do not update MailNickname column, this column contains mailnicknames for source tenant, and it is case sensitive. In case any objects are added by mistake, please remove entire rows related to these objects.
  • You can merge multiple source teams to a single target team. Just provide the same target team name in a mapping file.
  • File names with non-ASCII characters are not supported.
  1. Open Teams tab and click Map from File.
    Do not select any teams from the list – you have already specified them in the file created on Step 1.
  2. Click Browse to open the mapping file prepared on Step 1.
  3. Browse for file and click Open. Selected file name appears next to the Browse button.
  1. Schedule when the task will be started. See Task Scheduling for details. Click Next to view task summary.
  2. Check selected options. Click Finish to save or start the task depending on schedule option selected.

The task is created. You can track the progress in the Tasks list or view the summary on the Dashboard.

Creating Mapping File
  1. Prepare a comma-separated values (CSV) file with the matched teams pairs. The first row defines the names of the source and target attribute used for mapping. Subsequent rows list the matching values of the attributes (one pair per row.) This file should have two columns

Target Team Name, MailNickName

Example_Name,SampleName

Target Team Name specifies team name, e.g., Example_Name, you want your source team ( in this example the source team with mailnickname SampleName) to be matched in target tenant.

MailNickname specifies your source tenant team MailNickname, e.g., SampleName. This field is case sensitive.

 NOTE: File names with non-ASCII characters are not supported.

 

Pre-Migration Assessment for Teams

On Demand Migration analyzes your environment and tracks potential problems, misconfiguration, and risks that might adversely affect the migration. Use Assessment view to see the summary reports on the discovered data and use the automatic filters to quickly select certain items.

The following reports are available for Teams:

  • Workflow - Teams sorted by completed workflow
    • Discovered
    • Processed
    • Migrated
  • Teams- Teams sorted by processing status
  • Idle
  • In progress
  • Needs your attention
  • Teams By Size
  • Teams By Last Activity Time
  • Teams By Channel Count
  • Teams By Member Count

Once you handle the issues, if any, go to List View screen. You are ready to start the migration.
