We work with Oracle teams running complex, production environments. We know a forced migration under deadline pressure is not a small thing. Here is what your options actually look like and why Tessell is the managed alternative built for this transition.
AWS will discontinue RDS Custom for Oracle on March 31, 2027. The deprecation period began on March 31, 2026 - giving customers a 12-month window to migrate, of which a significant portion has already passed. Tessell is the managed alternative. RDS Custom existed for a specific reason - Oracle teams needed OS-level access and deeper database control alongside a managed service. Tessell preserves all of that - running inside your own AWS account, fully managed, with migration handled for you. Tessell is a fully managed database service - meaning Tessell handles all database operations including patching, backups, high availability, and disaster recovery, while your databases and data remain entirely within your own AWS account. AWS's recommended path is self-managed Oracle on EC2. If you'd prefer to stay managed, that's Tessell.

Each option preserves something different from what RDS Custom gave you. The right fit depends on how much operational control you want to keep versus hand off.
Managed, but without the control. RDS for Oracle keeps patching, HA, and DR handled for you, while closing off the deeper access RDS Custom allowed.
