25251. Go to [**Claude's access > Channels**](https://claude.ai/admin-settings/claude-tag?access=channels). A workspace or channel set to Legacy shows **legacy Claude in Slack** in the **Changes from defaults** column.
26262. Open each one, and on its **Advanced** tab set **Claude Tag version** to **New**.
273. The **Slack** row never shows that marker, so also go to [**Claude's access > Channels > Slack**](https://claude.ai/admin-settings/claude-tag/channels/slack) and set **Claude Tag version** on its **Advanced** tab to **New** if it shows **Legacy**.

47> Since October 5, 2026, the earlier Claude in Slack app, shown as **Legacy** in admin settings, no longer answers in channels of a workspace paired with your Claude organization. A channel there that's still set to Legacy gets a notice that the legacy bot is retired, until you set **Claude Tag version** to **New** on the channel, or on its workspace if the channel inherits the setting. You also can't switch a workspace or channel to Legacy anymore. Direct messages aren't affected. In a workspace that isn't paired, Pro, Max, and Ultra users still get answers from the earlier app in channels, and anyone else with a connected Claude account gets the [workspace setup notice](https://claude.com/docs/claude-tag/admins/troubleshooting.md#this-workspace-isn%E2%80%99t-set-up-for-claude-tag-yet) instead.

71The earlier Claude in Slack and Claude Tag are two versions of the same `@Claude` Slack app, not two apps, so there is nothing to uninstall. You choose which version answers in each workspace and channel with the **Claude Tag version** setting. Set it to **New** or **Inherit**. A workspace or channel can't be switched to **Legacy**, and one that's still on Legacy gets the retirement notice in channels instead of answers. Turning off a workspace's or channel's enable switch silences both versions there.

7373To tell which version answered in a channel, look at who authored the work. The New version authors code as the Claude GitHub App and keeps work in the channel's thread; if `@Claude` still opens pull requests under the asker's name, that channel is answering with the Legacy version.
