Looker to Sigma: 30+ Dashboards Consolidated to 8 Reports in Just 3 Weeks
Aimpoint Digital migrated Advisr's customer-facing Looker reporting suite to Sigma in three weeks, consolidating 30+ dashboards into 8 focused reports and cutting ongoing maintenance effort by over 70%.
The Challenge
Advisr, a marketing technology company, needed to sunset Looker as the embedded reporting solution in their customer portal on an aggressive timeline. The team had already completed foundational work migrating data models and transformations to BigQuery. But translating and rebuilding customer-facing Looker dashboards in Sigma presented a distinct problem. Complex LookML logic, built up over time to serve a diverse set of reporting needs, made a straightforward lift-and-shift impractical. With limited internal Sigma expertise and a hard deadline approaching, Advisr needed a partner who could move fast without cutting corners, and who understood both the platform they were leaving and the one they were moving to.
Our Approach
Aimpoint Digital deployed a lead analytics consultant with deep expertise in both Looker and Sigma to guide Advisr through the migration.
Inventory and Prioritization: Work began with a full inventory of the Looker reporting suite and underlying LookML, conducted alongside Advisr's Manager of Reporting and Analytics to quantify and prioritize the dashboards required for migration.
Consolidation Over Replication: Rather than executing a traditional lift-and-shift, Aimpoint developed a strategy that used Sigma's native capabilities to improve the reporting experience. The team consolidated 30+ Looker dashboards into 8 focused Sigma reports, delivering a cleaner portal experience while cutting the surface area the analytics team would need to maintain by over 70%.
Parallel Delivery and Coaching: Migration work ran in parallel with Advisr's analytics team, accelerating delivery while building Sigma knowledge through 15+ hours of hands-on, one-on-one coaching. When the engagement concluded, Advisr's team had the skills and confidence to own their Sigma environment going forward.
"Working with Aimpoint to migrate from Looker to Sigma was the smoothest tool transition I've ever experienced. They helped us consolidate an entire suite of Looker dashboards into 8 simplified and user-friendly Sigma dashboards, without losing any of the complex logic we had built in LookML. Their ability to quickly understand our setup and deliver a clean, efficient solution was unmatched."
Results
Advisr's 30+ high-priority, customer-facing Looker dashboards were consolidated into 8 focused Sigma reports. New reports preserved all complex LookML logic while delivering a cleaner, more intuitive experience for portal users.
By rationalizing redundant dashboards and using Sigma's native capabilities, the migration cut ongoing maintenance effort by over 70%. Sigma's lower barrier to entry meant Advisr's existing team could build and maintain reports without specialist LookML skills, saving roughly $150k a year in headcount they would otherwise have needed. That freed the analytics team to focus on new work rather than supporting legacy reports.
Through 15+ hours of one-on-one coaching delivered alongside the migration, Advisr's analytics team built the fluency to own, maintain, and grow their Sigma reporting environment independently. The value of the migration extends well beyond the three-week engagement.
Key Takeaways
A platform migration does not have to mean months of disruption followed by a reporting environment that looks exactly like the one you left. Advisr's Looker retirement proved that a migration can be an opportunity to rationalize, consolidate, and improve, not just replicate. And all that within pressing commercial timelines.
The 73% consolidation ratio and 70%+ maintenance reduction came from pairing deep platform expertise in both Looker and Sigma with a deliberate decision to rethink the reporting suite rather than copy it. That approach turned a three-week sprint into a lasting structural improvement.
