Question 1

1. How do I migrate from Slack to Microsoft Teams?

Accepted Answer

To migrate from Slack to Microsoft Teams, you need to connect both your Slack workspace and your Microsoft 365 tenant to a migration tool, map users, select the channels and direct messages to migrate, and run the migration.

Question 2

2. Can Microsoft’s free Slack migration tool migrate direct messages?

Accepted Answer

No. Microsoft’s native Slack to Teams migration tool only migrates channel content, including public and private channels, channel messages, and channel files. To migrate Slack direct messages, group direct messages, and rich metadata and context, organizations need to use the third-party migration tool like CloudFuze that has API-level access to direct messages and the ability to map them to Teams personal chats.

Question 3

3. How Much Does It Cost to Migrate from Slack to Teams?

Accepted Answer

The cost to manage Slack to Teams depends on the number of users, the volume of data (messages and files), the level of metadata preservation required, and whether you want to use Microsoft’s free native tool or a third-party platform. Microsoft’s admin center tool is free but limited to channels. CloudFuze pricing is scoped based on user count and data volume.

Question 4

4. How long does a Slack to Teams migration take?

Accepted Answer

Migration time depends on data volume, the number of users, and the number of messages and files. Small migrations (under 500 users with monitored data) typically complete within a week. Large enterprise migrations can take several weeks and months, particularly when data migration and validation phases are included.

Question 13

13. How do IT admins handle multi-workspace Slack environments when migrating to a single Microsoft Teams tenant?

Accepted Answer

CloudFuze connects to all workspaces in a Slack Enterprise Grid and migrates them into one Microsoft 365 tenant. Each workspace maps to its own Teams in Microsoft Teams, so IT admins don’t need to run separate migration projects per workspace.

Question 14

14. Can users continue using Slack while the migration runs in the background?

Accepted Answer

Yes. CloudFuze migrates data in the background while users keep working in Slack. After the one-time migration, a delta migration moves the messages sent since it started, so users don’t lose access or history during the move.

Question 15

15. How do you handle inactive or archived Slack channels prior to migration?

Accepted Answer

CloudFuze helps migrate archived channels directly, without requiring them to be unarchived first. For inactive channels that you do not want to carry over, you can exclude them from the migration scope during planning.

Question 16

16. How are private Slack channels handled during a Microsoft Teams migration?

Accepted Answer

Private Slack channels migrate as private channels in Microsoft Teams, with access limited to their original members. When a team combines public and private Slack channels, CloudFuze sets the destination channel security to private to keep that access restricted.

Question 17

17. Can we migrate direct messages and self-messages from Slack into Teams?

Accepted Answer

Yes, CloudFuze migrates one-to-one and group direct messages from Slack to Microsoft Teams.

Question 18

18. How does a delta migration prevent data loss if users keep chatting on Slack during the move?

Accepted Answer

Till the migration runs after the one-time migration and transfers any new messages sent since it started, so that the conversations that continued in Slack during the migration still land in Teams.

Question 19

19. What happens to Slack message threads, emojis, and pin states?

Accepted Answer

CloudFuze preserves threads, replies, emojis, and pinned messages in both channels and DMs during migration.
