“Migrating an entire database is a pretty bold and risky endeavor. Our main priorities — and challenges — were to do a complete data platform migration, as well as add in scalability and flexibility without disrupting the platform or hindering data security. Amazingly, using MongoDB Relational Migrator, we didn't experience any disruption or downtime.”
