This is one way to migrate contents from a SharePoint Discussion Board list to Yammer Platform
- Generate a Developer Token in Yammer (https://www.yammer.com/client_applications)
- Decode the Yammer GroupId Base64
$GroupId = 'eyJfdHlwZSI6Ikdyb3VwIiwiaWQiOiIyNzY0NDcxNTAwOSJ9'
$decoded = [System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String($GroupId))
Write-Output $decoded
- Export Discussion Board list items in XLSX extension
- No Reply messages will be migrated (Only the body of the discussion)
