Database Migration to OCI: Benefits and Solutions

Table of Contents

    Overcome the struggle of managing on-premises databases by moving to Oracle Cloud Infrastructure (OCI). Database Migration to OCI is a cost-effective solution that offers streamlined performance and effortless scalability.

    In this blog, we will explore the benefits of Database Migration to OCI and solutions for smoother and successful transition.

    Why Migrate your Databases to OCI?

    Let’s find out the benefits of OCI Database Migration.

    Simplified Migration Scenarios

    Database migration procedures are made simpler by its robust orchestration automation, source and target compatibility diagnostics and repair, and a unified user experience. It helps to eliminate operational disruption by performing short or long-term migration scenarios with or without database downtime.

    User-friendly

    It eliminates the need to learn Oracle’s portfolio of enterprise-class Database Migration tools and offers simplified complex situations, which are accessible to all users. It validates database metadata through built-in source and target compatibility diagnostics and enables interactive problem resolution.

    Cost-effective Solution

    Oracle’s Database Migration is a comprehensive and reliable service that is available at an affordable price to move your data into OCI. Plus, it is free for six months per migration.

    Leverage The Benefits of Database Migration to OCI.

    Consider Oracle-certified partners like Astute for optimum benefits.

    OCI Database Migration Workflow

    OCI Database Migration helps to move Oracle databases from on-premises or cloud deployments to OCI. The user-friendly graphical UX helps to validate and manage migration workflows. It provides secure, fault-tolerant, and incremental migrations by using Zero Downtime Migration, Cloud Premigration Advisor Tool, Data Pump, and GoldenGate services.

    Here, it is explained thoroughly.

    Sources and Targets

    It supports different sources like the standard edition, enterprise edition, Amazon RDS, and Exadata Database Machine. In OCI targets, you will get Exadata Cloud Service, Autonomous Database, and Oracle Base Database Service. Creating version upgrades and changes to target platforms becomes easy with the flexibility of logical migration.

    Migration Workflows and OCI Targets

    Without the help of advanced DBA skills, migration workflows can fulfill the operational requirements. Migration is possible in different conditions, whether your applications are online, offline, or across the Firewalls. There is constant availability of source and target data for operating longer migrations.

    Additionally, if the migration includes modernization, workflows will also allow for version upgrades and hardware platform changes.

    Integrated Migration Advisor

    An extensive diagnostic advisor is integrated into the migration workflow. It prioritizes exceptions, suggests resolutions, and generates repair scripts. It enables users to review the details interactively, and they can ignore the warnings, exclude source objects, or choose to make repairs. This crucial step helps to simplify the migration workflow.

    7 Phases of Database Migration

    Let’s discover the different phases of Database Migration.

    • Validate

      It works to validate the source and target database, Data Pump configuration, and GoldenGate Hub, if relevant.

    • Prepare

      Creates required directory objects for Data Pump and a DB link, if relevant. Get ready and start the GoldenGate extract process. If necessary, it will enable you to do supplemental logging.

    • Export Initial Load

      It starts Data Pump Export on the source database and also monitors it.

    • Upload Data

      It transfers Data Pump dump files from the source to the OCI OSS.

    • Import Initial Load

      In this stage, it works on importing Data Pump dumps to the target database, either from the OCI OSS bucket or through DBLINK. Plus, it monitors the progress of Data Pump import.

    • Post Initial Load

      It facilitates the elimination of directory objects and provides credentials and DBLINK, which are built for Data Pump via Database Migration.

    • Clean-up

      Autonomous Database access to the wallet is removed from Database Migration.

    After completion of all seven phases, it is possible to validate data in the target database. The Object Storage bucket specified in the migration job receives the uploaded Data Pump import log file. It becomes easy to download the migration job log file from the console on the same page where the job was initiated.
