A major banking corporation needed to migrate a large amount of data from two EMC DMX’s to a Pure Storage array. The company had budget issues that required them to perform this migration without the support of a third-party data migration vendor. In addition, the SAN was located in a tightly controlled data center where existing fibre channel connections could not be touched. CDS provided some installation support and trained the customer in the migration configuration and cutover process of DMS, after which they were able to perform the entire process with very little remote support. Since OS upgrades took priority during the maintenance window, migration was put off until those upgrades were performed, where only a limited number of client hosts were included in each migration “wave.”
In the end, there were no production outages during the insertion or migration process, and there was no noticeable impact to production. Despite tight deadlines and priority given to functions other than migration, the project was completed on time and with a significant cost savings since the customer performed the migration directly.
