What is database migration services?
Database migration services move your data safely between versions, platforms or environments — for example SQL Server to PostgreSQL, Oracle to Aurora, or on-premise to Azure SQL. NNT Software plans, rehearses and validates every migration so data is complete, applications keep working and downtime is kept to minutes.
Low-risk database upgrades, cross-platform migrations and on-premise to cloud moves with data validation and minimal downtime.
