Import from Slack (beta)

Starting with Zulip 1.8, Zulip supports importing data from Slack, including users, channels, messages, attachments, avatars, custom emoji, and emoji reactions.

Note: You can only import a Slack workspace as a new Zulip organization. In particular, you cannot use this tool to import from Slack into an existing Zulip organization.

Import from Slack

First, export your data from Slack.

  1. Export your Slack data. You will receive a zip file slack_data.zip.

    !!! warn "" Note: Only Slack owners and admins can export data from Slack. See Slack's guide to data exports for more information.

  2. Generate a Slack API token.

Import into zulipchat.com

Email support@zulipchat.com with slack_data.zip, the Slack API token generated above, and your desired subdomain. Your imported organization will be hosted at <subdomain>.zulipchat.com.

Import into a new Zulip server

!!! warn "" Because the Slack import tool is very new, we recommend first upgrading your new Zulip server to the latest master branch, using upgrade-zulip-from-git to avoid bugs in the earliest versions of the Slack import tool.

Log in to a shell on your Zulip server as the zulip user. Run the following commands, replacing <token> with the value generated above:

cd /home/zulip/deployments/current
./manage.py convert_slack_data slack_data.zip --token <token> --output converted_slack_data
./manage.py import --destroy-rebuild-database '' converted_slack_data

!!! warn "" Warning: This will destroy all existing data in your Zulip server

Import into an existing Zulip server

If you already have some organizations hosted on your Zulip server, and want to add import your Slack data as a new Zulip organization, you can use the following procedure.

Log in to your Zulip server as the zulip user. Run the following commands, replacing <token> with the value generated above, and <subdomain> with the subdomain of the URL you'd like for your imported Zulip organization.

cd /home/zulip/deployments/current
./manage.py convert_slack_data slack_data.zip --token <token> --output converted_slack_data
./manage.py import --import-into-nonempty <subdomain> converted_slack_data

Caveats

  • Slack doesn't export private channels or direct messages unless you pay for Slack Plus or contact Slack support. See Slack's documentation for more details.

  • (Slack Plus import) Private channels and direct messages are currently not imported. We expect to address this in a future revision.

  • (Slack Plus import) Message edit history is currently not imported.

  • Slack doesn't export user settings or organization settings, so you'll need to configure these manually.

  • Permission hierarchy: Slack's Primary owner, owner, and admin are mapped to Zulip's Organization admin. Slack's Member, restricted, and ultra restricted are mapped to regular Zulip users. Channel creators have no special permissions in Zulip.

  • The "joined #channel_name" messages are not imported.
