Yes, you can definitely restrict what you migrate or move when working with multiple databases. In most cases, you don’t have to move everything, you can select specific tables, schemas, or even individual records based on your needs.
For example, during a migration, I usually define clear data selection rules or filters, like only moving active customer data, or excluding historical logs that aren’t needed in the target system. Most modern ETL and data migration tools allow fine-grained control over what gets transferred, so you can manage scope, performance, and cost effectively.
When dealing with multiple databases, I also make sure to handle dependencies and relationships carefully that ensure that partial migrations don’t break referential integrity. Overall, it’s about planning what really needs to move and setting up the right configurations so the migration is efficient, consistent, and secure.
Data migration services also follow similar principles that focus on selective movement, data integrity, and efficiency to ensure a smooth transition between systems.
