Issue Summary

After migrating data from one Slack workspace with Slack integration to another it adds a connection to a channel in an old Slack workspace instead of to a new one.

Steps to Reproduce

1. Create a connection for channel #test in Slack workspace A.
2. Migrate data from Slack workspace A to Slack workspace B.
3. Remove the connection for channel #test in Slack workspace A.
4. Create a new connection for the same channel #test but in Slack workspace B.

Expected Results

It should create a connection for channel #test in Slack workspace B.

Actual Results

It creates a connection for channel #test in Slack workspace A instead of B.

Workaround

Unable to subscribe to Slack channel after workspace migration

• Users can create a new channel in a new Slack workspace and create a connection there or use the channel which didn't have any connections when it was part of an old Slack workspace.
• Reach out to support (the engineering team can perform a manual clean-up on their side).
