Case Study: a leading Danish bank achieves zero-disruption Tableau Cloud migration with Biztory and TabMove

a leading Danish bank migrates 8,241 workbooks to Tableau Cloud with Biztory

A leading Danish bank faced the challenge of migrating its massive on-premise Tableau Server environment to Tableau Cloud. With over 30,000 users relying on 8,241 workbooks, the bank needed to consolidate 126 sites, maintain strict security, and ensure zero business disruption during the migration. They partnered with vendor Biztory to de-risk this complex project.

Biztory implemented a solution using its proprietary TabMove tool, executing the migration in a series of structured waves. This approach successfully moved all workbooks and data sources to a single, unified Tableau Cloud environment. The result was a seamless transition for all users, centralized governance integrated with the bank's IAM tooling, and a significant reduction in IT overhead, all achieved without any interruption to daily financial operations.
