What happens to the message history of Walsh Global after migrating to MCC’s Enterprise Grid settings?

When Walsh Global migrates to MCC’s Enterprise Grid settings, messages older than one year will be lost. This is due to the specific retention policies that can be configured within Slack's Enterprise Grid. When a workspace is moved to Enterprise Grid, it can apply different settings that dictate how long messages and files are retained. Slack’s default retention policy retains messages for a specified period, and if the organization chooses a policy that deletes old messages beyond a one-year threshold, those older messages will indeed be lost in the transition.

This approach ensures compliance with data management policies and enhances security, but it can also lead to the permanent loss of historical message data for users unless proper measures are taken beforehand to archive or export necessary information. Therefore, understanding these retention settings is crucial for organizations transitioning to new Slack configurations and can impact how historical data is managed.
