When you migrate from Slack to Microsoft Teams with ZuniPixel, nothing is left behind.

Public channels

All messages, threads, files, and full channel history migrated to the correct Teams channel.

Private channels

Full private channel history migrated with permissions and memberships preserved end-to-end.

Direct messages

1:1 and group DMs migrated to Teams. No Microsoft Teams authentication required — Slack auth only.

User mentions

@mentions preserved and mapped accurately to the correct user accounts in Microsoft Teams.

Why ZuniPixel

Three capabilities no other Slack migration tool has

The technical differentiators that make ZuniPixel the only tool built specifically for how enterprise IT admins actually run migrations.

Direct message migration

Migrate Slack DMs — no Teams authentication needed

Most migration tools require every employee to authenticate in both Slack and Teams before a single DM moves. ZuniPixel only needs Slack.

Migration speed

Smart rate limiting — maximum speed on both APIs

ZuniPixel manages Slack and Teams API rate limits simultaneously — running as fast as both platforms allow, without triggering throttling on either side.

Enterprise migration

JSON-based migration — no Slack API, no rate limits

For large enterprise migrations, ZuniPixel reads from a Slack JSON export — bypassing the Slack API entirely. No API calls, no rate limits, no authentication required on either side for DMs.

Security

Your Slack data never leaves your control

ZuniPixel is built on the principle that your message data belongs to you — not us.

OAuth 2.0 authentication

All Slack and Microsoft Teams connections use OAuth 2.0. ZuniPixel never handles or stores passwords or credentials. Authentication tokens are scoped to the minimum permissions required for migration.

End-to-end encryption

All data in transit between Slack, ZuniPixel, and Microsoft Teams is encrypted end-to-end. Your messages, channel content, and direct messages are never transmitted in plain text at any stage of the migration.

Zero message storage

ZuniPixel does not store your Slack messages, direct messages, or channel content at any point. Data moves directly from Slack to Microsoft Teams — we are a conduit, not a repository. Nothing is retained after migration completes.

Two ways to migrate

Migrate yourself — or let us run it

One platform. Two paths. Both get you from Slack to Teams without data loss.

Recommended — reduce migration costs

Self-service migration

Migrate your entire Slack workspace to Microsoft Teams yourself — without a managed services contract or professional services fees. ZuniPixel's guided UI takes you through every step, with full batch control, CSV mapping, scheduling, and reporting throughout.

  • Guided setup — connect, pre-scan, map, and migrate
  • CSV channel mapping — map 500+ channels in one upload
  • Batch creation and scheduling — your timeline, your control
  • Granular reporting at every stage
  • No vendor dependency — cancel any time
  • Fraction of managed migration costs

Frequently asked questions

Everything you need to know about Slack to Teams migration

Yes — ZuniPixel migrates Slack direct messages (1:1 and group DMs) including full message history, files, emojis, and timestamps. What makes ZuniPixel different is how DM authentication works: API-based migration requires Slack user authentication, but Microsoft Teams authentication is not required. JSON-based migration requires no authentication on either side because ZuniPixel reads directly from a Slack JSON export.

JSON-based migration is ZuniPixel's API-free migration path. Instead of calling Slack's APIs, ZuniPixel reads directly from a Slack JSON export file, which includes all channels, messages, members, and direct messages. Use it for enterprise teams with large data volumes or SMB teams that want to stop paying Slack licenses immediately.

Slack and Microsoft Teams both enforce API rate limits. ZuniPixel actively monitors both platforms' API thresholds in real time and runs your migration at the maximum speed both platforms will allow, automatically adjusting without human intervention.

ZuniPixel is built for IT admins to run independently — no managed services contract required. The self-service path gives you guided setup, CSV channel mapping, batch creation and scheduling, and granular reporting. Managed migration is available for 10,000+ user or complex compliance projects.

ZuniPixel migrates public channels, private channels, direct messages, threads and replies, emojis and reactions, user mentions, channel permissions and memberships, and user identity. Slack-specific features with no Microsoft Teams equivalent, such as native Slack app integrations and Slack workflows, cannot be replicated by any migration tool.

ZuniPixel is built on OAuth 2.0 authentication, end-to-end encryption, and zero message storage. ZuniPixel does not store your Slack messages, DMs, or channel content. Data moves directly from Slack to Teams, and nothing is retained after migration completes.
