I have been testing the V2 New Workspace Power BI and mainly use it for review our Power BI reports' usage metrics. These metrics are able to help both our IT and business owners to either showcase how often users utilize the report or provide a case to decommission a report due to low usage. I noticed that the data retention for the new version is only 30 days. On the other hand, the V1 Classic Workspace has the capability to hold and display data from the past 90 days. The longer retention period is extremely valuable for our usage metrics and this would prevent our team from having to store the usage metrics outside of the V2 New Workspace Power BI to give us the 90 day historical view.
