+## EDB Data Migration Service
 
-The [EDB Data Migration Service](data-migration-service) is a cloud-based service that actively helps you migrate your data to Postgres.
+[EDB Data Migration Service](data-migration-service) is a cloud-based service that helps you migrate your data to an [EDB Hosted Cloud Service](/edb-postgres-ai/cloud-service/getting_started/planning/choosing_your_deployment/edb_hosted_cloud_service/) database.
 
-## The EDB Postgres AI Migration Portal
+EDB DMS offers a secure and fault-tolerant way to migrate database data to the EDB Postgres AI platform using change data capture and event streaming technologies. This allows the migration to stream any changes in the source database to the EDB Cloud Service database until you decide to cut over.
 
-The [EDB Postgres AI Migration Portal](/migration_portal/latest/) is a web-based tool that helps you plan and execute your migration to Postgres.
+At the end of a data migration with EDB DMS, the data in your source database will have been copied to a Postgres database managed with EDB Postgres AI Cloud Service.
 
-EDB Postgres® AI Tools Migration Portal offers an [AI copilot](/migration_portal/latest/03_mp_using_portal/mp_ai_copilot/) to assist users who are migrating their databases to EDB Postgres. 
-The AI copilot is an AI-driven chatbot tool that helps users with the migration process. 
-The AI copilot is designed to help users with the following tasks:
+- **Purpose:** Migration of database data
 
-- **General migration assistance**: The AI copilot can help users with general migration questions. 
-  For example, users can request information about available tools, and source and target database compatibility.
-- **Migration planning**: The AI copilot can help users plan their migration, and obtain an overview of the end-to-end migration paths.
-- **Migration assessment**: The AI copilot can help users assess their migration readiness. 
-  For example, if there are compatibility issues between source and target databases, the AI Copilot can suggest compatible query alternatives. 
+- **Applicable migration scenarios:** From Oracle, PostgreSQL or EDB Postgres Advanced Server to [EDB Hosted Cloud Service](/edb-postgres-ai/cloud-service/getting_started/planning/choosing_your_deployment/edb_hosted_cloud_service/) databases with PostgreSQL, EDB Postgres Advanced Server or EDB Postgres Extended Server
 
-The AI copilot is designed to be user-friendly and easy to use. Users can interact with the AI copilot using natural language and improve the quality of answers with [good prompting](/migration_portal/latest/03_mp_using_portal/mp_ai_copilot/ai_good_prompts/). The AI copilot is also designed to be context-aware, so it can provide users with relevant information based on the context of the conversation.
