5 min read Updated on December 1, 2024 Cloudiway Team

Overview

The Cloudiway platform facilitates migrating Slack workspaces to Microsoft Teams, providing flexible options to map your Slack channels to Teams structures. Whether you're consolidating workspaces or transitioning your entire organization to Teams, Cloudiway offers three distinct migration approaches.

What Gets Migrated

Cloudiway's Slack migration transfers comprehensive workspace content to Microsoft Teams:

Channels

  • Standard (public) channels
  • Private channels

Content

  • Messages and threads
  • File attachments

Direct Messages

  • 1:1 direct messages
  • Group direct messages

Conversation Handling

  • Injected directly into Teams
  • Overflow archived as HTML

Message Volume Options

Performance settings allow you to limit the number of messages injected directly into Teams channels. Additional messages beyond the limit are archived as HTML files for reference.

Migration Options

Cloudiway offers three distinct approaches for mapping Slack channels to Microsoft Teams structures:

Option 1: Team-Level Migration

Migrate Slack channels into a Microsoft Team's default General Channel.

How It Works

  • Specify only the Team name in the target field
  • The system creates the Team if it doesn't exist
  • Slack channel content migrates to the General channel
  • Best for: Simple migrations with few channels per workspace

Option 2: Specific Channel Migration

Map Slack channels to specific channels within a Microsoft Team.

How It Works

  • Enter both the Team name and Target Channel Name
  • The platform creates missing Teams or channels during preprocessing
  • Maintains 1:1 mapping between Slack and Teams channels
  • Best for: Preserving channel structure after migration

Example Mapping

#marketing Marketing Team / General
#marketing-social Marketing Team / Social Media
#marketing-content Marketing Team / Content

Option 3: Private Channel Migration

Migrate Slack private channels to Microsoft Teams private channels.

How It Works

  • Enable the "Migrate to Private Channel" option
  • Map Slack private channels to Teams private channels
  • Preserves the private nature of the content
  • Maintains membership restrictions
  • Best for: Confidential team discussions and projects
