To sum it up in three words – slowly and manually.
Without an automated BI intelligence platform like Octopai, BI groups have to take a manual approach to migrating to Power BI and all the activities associated with it. This means going through your legacy reporting tool, report by report, in order to:
• Eliminate reports that simply aren’t needed anymore
• Identify redundancies, obsolete or unreliable data sources
• Target ETL processes that fail to capture relevant data or combine it effectively with other data
It requires detective work, combing through logs and job schedules in disparate systems and examining stored procedure code, report definitions, etc. All of this background work can take weeks and more often than not, months. And because the company’s data landscape is always changing, BI and analytics teams end up chasing a moving target. Migration to Power BI can only be truly successful, efficient, and accurate with an automated BI intelligence platform that comprises automated data discovery, data lineage and business glossary.
