# Upgrade from Slack V1 (legacy)

**Available on:** Standard, Pro, Enterprise plans.

The original Slack integration (V1), which answered a slash command such as `/chatthing`, is deprecated. New Slack channels always use the current integration. If your bot still uses V1, upgrade it to get @mentions, direct messages, the assistant sidebar and the Slack power-ups.

**Who can do this:** [team owners and admins](https://chatthing.ai/docs/account/teams#what-each-role-can-do).

## Check which version your bot uses

Open your bot, select the **Channels** tab and click the settings (cog) icon on the **Slack** card. If a **Slack Channel Settings** window opens with the message "This channel is using our v1 old Slack integration", your bot uses V1. If the full **Slack channel settings** page opens instead, you're already on the current integration.

## Upgrade to the current integration

1. Remove the old V1 app from your Slack workspace: go to your [Slack apps](https://api.slack.com/apps), open the old app and choose **Delete App**.

2. In Chat Thing, open the Slack channel settings and click **Upgrade to V2 Slack Integration**.
3. Set up the new Slack app by following [Add your bot to Slack](https://chatthing.ai/docs/channels/slack#connect-your-bot-to-slack).

After upgrading, people talk to the bot by mentioning it (for example `@botname`) or messaging it directly, instead of using the slash command.

## Check it works

Send the bot a direct message in Slack. It should reply without a slash command.
