Hi Jack,
If you want to move the Report builder tables to power BI use (Power Pivot add in) for more detail refer below link;
Get data using the Power Pivot add-in - Excel
In Power BI Desktop, you can connect to Adobe Analytics and use the underlying data just like any other data source in Power BI Desktop

Steps to connect refer below link;
Connect to Adobe Analytics in Power BI Desktop - Power BI | Microsoft Docs
Note: If you don't have Power BI, then your data get stored in Cloud (Maybe your customer data shared is not secured)
Please check the steps to share datasets in Power BI
Create and share datasets (Preview) - Power BI - Power BI | Microsoft Docs
