Seamless and Smooth Sybase to Oracle Migration (on Prem to Cloud)

We often face database migrations and have to deal with various issues like data type incompatibility, version issues, database size and restrictions regarding downtime, performance on the new platforms, and special requirements associated with the application, to name just a few. A database migration, if well-planned and executed, can be very smooth and seamless. Platform migration can add value, such as increased performance on the destination platform. A migration can also end up with an excruciatingly long and tedious process plagued with errors and failures – in short, a nightmare. After managing many migrations from various database technologies, one assembles a few main tasks to focus on and tips and tricks to ensure a smooth migration. Using a few use cases from the federal space, I would like to highlight some methodologies I have followed to create a repeatable Sybase to Oracle migration process, which you can apply to any database migrations.
