Full migration coverage

Every content type — migrated and preserved

When you migrate from Slack to Google Chat with ZuniPixel, nothing is left behind.

Channels & Spaces

Slack channels become Google Spaces — with structure, membership, and full conversation history intact.

Public Slack channels → Google Spaces
Private channels → Restricted Spaces
Channel membership and roles preserved
Pinned messages and channel topics
Rename of Space during mapping

Messages & Threads

Complete conversation history migrated with full attribution — every reply, reaction, and mention preserved.

Full message history with original timestamps
Threaded replies as Google Spaces threads
Direct messages — 1:1 and group DMs
Emoji reactions preserved
User @mentions mapped to Google accounts

Files & Users

Files migrate into the corresponding Space. Larger or unsupported files route to Google Shared Drive automatically.

Files under 200MB migrate directly into the Space
Files over 200MB migrate to Google Shared Drive
Unsupported formats migrate to Google Shared Drive
Links to files appear in Space conversations
Slack users matched to Google Workspace accounts

Platform capabilities

Built for IT teams running enterprise migrations

ZuniPixel gives your team the visibility and control that generic migration scripts can't provide.

Security & architecture

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

Token-based access to both Slack and google spaces. ZuniPixel never handles or stores passwords or credentials. Tokens are scoped to the minimum permissions each job requires and revoked immediately once it completes.

End-to-End Encrypted

All data transferred between Slack, ZuniPixel, and Google is encrypted in transit using AES-256. No plaintext data is exposed at any point — from the first API call to the final validation report delivered to your IT team.

Zero Data Retention

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

Frequently asked questions

Everything you need to know about Slack to Google Chat migration

Yes. ZuniPixel migrates both public and private Slack channels to Google Spaces, preserving channel membership, message history, threaded replies, and pinned messages.
Yes. Slack 1:1 direct messages are migrated to Google Chat 1:1 conversations. Slack group DMs are migrated to Google Chat group conversations. Complete conversation history is preserved, including file attachments, emoji reactions, and original timestamps.
Files shared in Slack channels are migrated into the corresponding Google Chat Space. Files over 200MB or in a format Google Chat doesn't support are automatically uploaded to Google Shared Drive, with the link inserted into the message.
ZuniPixel maps Slack users to their Google Workspace accounts so every migrated message is correctly attributed to the right person in Google Chat. You manage the mapping via the dashboard or upload a bulk CSV for large organizations. Unmapped users are flagged before the migration runs — nothing proceeds until the mapping is verified.
Yes. Admins can select which channels to migrate first and run the rest later. Batch-based migration is also available for larger, multi-batch rollouts. Delta sync catches any new messages in channels that have already been migrated between batches.
Bot and app messages migrate along with the conversation history. Bots and integrations need to be reconfigured manually in Google Chat.
Yes. Slack and Google Workspace connect via OAuth 2.0, so no passwords are stored. Data is encrypted in transit using TLS 1.2 or 1.3 and at rest.
