Migrating from Slack to Element represents a strategic shift from a proprietary, siloed SaaS tool to an open, decentralized communication platform built on the Matrix protocol. Organizations typically make this move to eliminate mounting per-user subscription fees that range from $7.25 to $15 per month, reclaim absolute ownership of their organizational data, and meet stringent compliance requirements that forbid third-party cloud data processing. Element offers persistent end-to-end encryption by default and the flexibility to self-host on internal infrastructure or utilize secure managed hosting.
While Slack offers immediate out-of-the-box convenience, its closed ecosystem limits deep customization and data portability. Element provides the same modern chat functionality—including threaded conversations, voice and video calling, and rich media sharing—without the recurring financial burden or vendor lock-in. Planning this migration requires a deliberate approach to account provisioning, channel mapping, and user re-training, as moving away from Slack means transitioning from a centralized proprietary database to a federated, decentralized network model.
Successful migration hinges on a phased rollout that moves core teams first, establishes clear Matrix homeserver parameters, and carefully phases out legacy Slack workspaces. By executing a structured transition plan, organizations can drastically reduce software overhead while simultaneously upgrading their data sovereignty and long-term communication security.
For a 50-person team that's a significant annual saving.
🗺️ Migration Steps
Begin by exporting your Slack workspace data using Slack built-in export tool, which is available in workspace settings depending on your current billing tier. Keep in mind that standard Slack exports typically include public channel history and uploaded file links, but private channel messages and direct messages require higher administrative privileges or compliance tools to extract.
Decide whether your organization will self-host a Synapse Matrix homeserver for maximum control or use Element Enterprise Hosted for a managed experience. Configure your authentication providers, set up user directories, and establish global retention policies that align with your corporate governance standards before onboarding any users.
Create a comprehensive mapping document that translates your Slack channels and user groups into Element room structures. Bulk create user accounts on your Matrix homeserver, and use automated provisioning scripts to match Slack display names and email addresses with your new Element credentials.
Use community-driven Matrix migration scripts or specialized ingestion tools to parse your Slack JSON exports and populate your new Element rooms with historical message archives. Because native import capabilities vary, prioritize importing vital project channels first while leaving older, archived Slack threads for manual reference if necessary.
Distribute Element client applications to your team members and conduct training sessions focused on Matrix security keys and cross-signing verification. During this transition window, you can deploy Matrix bridges to temporarily sync select Slack channels with Element rooms, allowing real-time communication between users still on Slack and early adopters on Element.
Set a firm deadline to disable your Slack workspace logins and transition all remaining staff exclusively to Element. Revoke remaining Slack API tokens, archive the legacy Slack workspace to prevent accidental usage, and direct all internal and external communication exclusively through your new Element infrastructure.
⚠️ Common Challenges & How to Avoid Them
Replace native Slack apps with Element widgets, custom Matrix bots, or Appservice bridges that connect to external services like GitHub, Jira, and Google Calendar.
Implement a centralized backup key recovery mechanism on your homeserver and provide clear, step-by-step internal documentation on how Element handles device verification.
Communicate clearly to your team that historical DMs will not transfer over, and encourage staff to manually copy any critical ongoing discussions before the Slack workspace is deactivated.

❓ Frequently Asked Questions
You can import public channel history using open-source Matrix migration tools that parse Slack JSON exports. However, due to Slack export limitations and privacy restrictions, direct messages and private channels generally cannot be automatically bulk-imported and often need to be archived for reference.
Element itself is free and open-source software, meaning you can self-host it at zero software cost aside from your server infrastructure. If you prefer a fully managed experience with enterprise support, Element offers paid hosting tiers that are typically significantly lower per user than Slack paid plans.
Element supports bridging and guest access, allowing you to invite external users into specific Matrix rooms via simple web links without requiring them to create a full account. For clients firmly rooted in Slack, you can maintain a bridged connection between a Slack channel and an Element room during transitional periods.
