Case Study: Isetan Mitsukoshi System Solutions achieves seamless database migration and lower costs with Amazon Web Services

Isetan Mitsukoshi System Solutions seamlessly migrates databases to Amazon Aurora using Amazon DMA

Isetan Mitsukoshi System Solutions needed to modernize complex legacy databases supporting EDI and customer service systems so it could focus on digital transformation. The company turned to Amazon Web Services, using Amazon DMA to help migrate to Amazon Aurora, while also working with Amazon RDS for Oracle and Amazon Aurora PostgreSQL.

Amazon Web Services completed the migrations in phased steps, resolving compatibility issues quickly and providing strong Japanese documentation and support. The EDI database moved in nine weeks as planned, and the customer service system migrated in 19 weeks within budget. Isetan Mitsukoshi System Solutions reported zero unplanned downtime after launch, better system performance, and lower costs from improved efficiency and the removal of expensive licensing fees.
