The Open edX Slack is a public Slack used by the entire community. Some of its channels are shared with other Slack instances, including the edX Slack, now owned by 2U.

2U is undertaking a migration of its private Slack workspaces. The original edX Slack (edx-internal.slack.com) will be retired, replaced with a new instance, twou.slack.com. The Open edX Slack (openedx.slack.com) will remain owned and administered by tCRIL for use by the community.

The 2U migration only affects the wider community where Slack channels have been shared with the edX Slack. Slack channels have an owning organization, and can be shared with other organizations. What happens to shared channels now depends on which organization owns the channel:

• Channels currently owned by edX will have to be re-created in the Open edX Slack, and then shared with 2U. The old channel will be renamed with an “old-” prefix, and the new channel will have the same original name. But this will mean you have to join the new channel, moving from the old edX-owned channel to the new Open-edX-owned channel. The old channel will be locked to ensure the discussion isn’t split between the old and new channels.

• Channels owned by Open edX can stay as they are, and simply be shared again with the 2U Slack. There will be no renaming, and you will not have to do anything.

• Some channels have fallen out of use, and will be abandoned.

You’ll notice that edX people who have the edX icon on their profile picture will soon be 2U people with a 2U icon. They are the same friendly helpful people they have always been!

The changes should all be made by the middle of November, but will be starting sooner than that.
