## Import your organization from Slack into Zulip
### Export your Slack data
Slack's [data export
service](https://slack.com/services/export) allows you to
export all public channel messages, **including older messages that may no
longer be searchable** under your Slack plan.
Unfortunately, Slack [only
allows](https://slack.com/help/articles/201658943-Export-your-workspace-data)
workspaces that are on the **Business+** or **Enterprise Grid** plans
to export private channels and direct messages. Slack's support has
confirmed this policy as of August 2022.
Owners of **Business+** or **Enterprise Grid** workspaces can [request
special
access](https://slack.com/help/articles/204897248-Guide-to-Slack-import-and-export-tools#options-by-plan)
in order to export direct message data.
{start_tabs}
1. Make sure that you are an owner or admin of your Slack
workspace. If you are one, the Slack web application will display
that in your profile, in a banner covering the bottom of your
avatar.
2. [Export your Slack message history](https://my.slack.com/services/export).
You should be able to download a `zip` file with your data a few minutes
after you start the export process.
3. You will also need to export your workspace's user data and custom emoji.
To do so, start
by [creating a new Slack app](https://api.slack.com/apps). Choose the "From
scratch" creation option.
4. [Create a
bot user](https://api.slack.com/authentication/basics#scopes),
following the instructions to add the following OAuth scopes to your bot:
- `emoji:read`
- `users:read`
- `users:read.email`
- `team:read`
5. [Install your new app](https://api.slack.com/authentication/basics#installing)
to your Slack workspace.
6. You will immediately see a **Bot User OAuth Token**, which is a long
string of numbers and characters starting with `xoxb-`. Copy this token. You
will use it to download user and emoji data from your Slack workspace.
!!! warn ""
You may also come across a token starting with `xoxe-`. This token cannot
be used for the Slack export process.

### Import your data into Zulip
{!import-your-data-into-zulip.md!}
{start_tabs}
{tab|zulip-cloud}
{!import-into-a-zulip-cloud-organization.md!}
1. Your Slack **Bot User OAuth Token**, which will be a long
string of numbers and characters starting with `xoxb-`.
{!import-zulip-cloud-organization-warning.md!}
{tab|self-hosting}
{!import-into-a-self-hosted-zulip-server.md!}
1. To import into an organization hosted on the root domain
(`EXTERNAL_HOST`) of the Zulip installation, run the following
commands, replacing `<token>` with your Slack **Bot User OAuth Token**.
{!import-self-hosted-server-tips.md!}
```
cd /home/zulip/deployments/current
./scripts/stop-server
./manage.py convert_slack_data /tmp/slack_data.zip --token <token> --output /tmp/converted_slack_data
./manage.py import '' /tmp/converted_slack_data
./scripts/start-server
```
Alternatively, to import into a custom subdomain, run:
```
cd /home/zulip/deployments/current
./scripts/stop-server
./manage.py convert_slack_data /tmp/slack_data.zip --token <token> --output /tmp/converted_slack_data
./manage.py import <subdomain> /tmp/converted_slack_data
./scripts/start-server
```
1. Follow [step 4](https://zulip.readthedocs.io/en/stable/production/install.html#step-4-configure-and-use)
of the guide for [installing a new Zulip
server](https://zulip.readthedocs.io/en/stable/production/install.html).
{end_tabs}
#### Import details
Whether you are using Zulip Cloud or self-hosting Zulip, here are few notes to keep
in mind about the import process:
- Slack does not export workspace settings, so you will need to [configure
the settings for your Zulip organization](/help/customize-organization-settings).
This includes settings like [email
visibility](/help/configure-email-visibility),
[message editing permissions](/help/restrict-message-editing-and-deletion),
and [how users can join your organization](/help/restrict-account-creation).
- Slack does not export user settings, so users in your organization may want to
[customize their account settings](/help/getting-started-with-zulip).
- Slack's user roles are mapped to Zulip's [user
roles](/help/roles-and-permissions) in the following way:
| Slack role | Zulip role |
|-------------------------|---------------|
| Workspace Primary Owner | Owner |
| Workspace Owner | Owner |
| Workspace Admin | Administrator |
| Member | Member |
| Single Channel Guest | Guest |
| Multi Channel Guest | Guest |
| Channel creator | none |
- Slack threads are imported as topics with names like "2023-05-30
Slack thread 1".
- Message edit history and `@user joined #channel_name` messages are not imported.
## Clean up after the Slack export
Once your organization has been successfully imported in to Zulip, you should
delete [the Slack app](https://api.slack.com/apps) that you created in order to
[export your Slack data](#export-your-slack-data). This will prevent the OAuth
token from being used to access your Slack workspace in the future.
## Get your organization started with Zulip
{!import-get-your-organization-started.md!}
!!! tip ""
Zulip's [Slack-compatible incoming webhook](/integrations/doc/slack_incoming)
makes it easy to migrate integrations.
