1. Schema Conversion
2. Access Control

Schema Conversion

• Schema Only Mode does not create foreign keys
• Migration of functions and views is not supported
• Schema recommendations are based on static analysis of the schema only

Access Control

• Spanner migration tool does not support database roles and privileges. If users wish to use Spanner fine-grained access control as an IAM principal, then they can manually create database roles, grant the appropriate memberships and privileges to these roles, and grant access to database roles to the IAM principal. Alternatively, users can grant database-level access to an IAM principal.
