Alibaba Cloud’s Advanced Database & Application Migration (ADAM) quantifies the database selection, migration risks, compatibility, and transformation workload to guide you through decision-making during the Oracle database migration. The three steps are listed below:
1. Business Research
Conduct research on the current databases and applications of your organization to assess the Oracle database migration. This process consists of background research, source database research, application research, and architecture research.
2. Feasibility Assessment
After the business research is completed, select an appropriate target database and formulate a detailed assessment plan to access the compatibility, performance, and migration risks of the target database.
3. Feasibility Verification
After the migration assessment is completed, select a representative module (such as the typical transaction settlement module) in the migration business, perform proof of concept (POC) testing on the target database to verify the feasibility of Oracle database migration, and issue a POC verification report.
Data Transmission Service (DTS) enables smooth database migration, ensures data accuracy and consistency, and supports business rollback upon anomalies. DTS can synchronize data in real-time, reducing system downtime and migration risks. The Oracle database migration contains three steps:
1. Business Transformation and Verification
After POC verification, conduct overall transformation, testing, and verification on the business system in terms of functions, performance, stability, reliability, security, scalability, migration plans, and rollback plans.
2. Cutover Drill
Conduct a cutover drill to test the functions, performance, and stability of the business system in a simulated release environment before production cutover. We recommend taking at least three to five cutover drills.
3. Production Cutover
Formulate cutover processes based on different business systems and assign process owners to take charge of each step to ensure successful production cutover.
Alibaba Cloud’s professional database service team can help you continuously monitor the business system and database to ensure smooth business operation and perform emergency troubleshooting and performance optimization. Also, we can create training plans as required.
This Oracle Database Migration solution mainly applies to OLTP. The destined cloud-native database PolarDB comprises PolarDB for MySQL, PolarDB for PostgreSQL, and PolarDB-O. They adopt the same architecture, but each one supports a different database engine. You can use ApsaraDB for PolarDB to innovate business successes.
ApsaraDB for PolarDB (PolarDB-Oracle) is a next-generation relational cloud-native database independently developed by Alibaba Cloud. It is highly compatible with the Oracle syntax engine, separates computing from storage, and supports scaling-up computing power to 1,000 cores and storage capacity to 100 TB. It integrates the stability, availability, security, and strong data consistency of centralized databases, and the flexibility and scalability of cloud-native databases.

Elasticity Management
ApsaraDB for PolarDB provides cloud-native elastic management capabilities. It enables cluster upgrade/downgrade, storage scale-in/scale-out, and in-service upgrade to enhance business write performance and reduce the risks of changing resource configurations by traditional means. With features such as automatic load balancing and read/write isolation, it automatically routes read/write business. It also allows you to flexibly add and remove read-only cluster nodes in service to deal with query requests at high queries per second (QPS) during peak hours.
Spatio-Temporal Processing
New business scenarios, including map services, vehicle monitoring, logistics distribution, and trajectory analysis, pose new requirements to the storage and management of time data and spatial geographical location data. Ganos is the powerful built-in spatio-temporal operation engine of ApsaraDB for PolarDB. It provides spatio-temporal data models, indexes, and operators that comply with SQL and SQL/MM standards to achieve unified storage and seamless association with business data and facilitate integration. The spatio-temporal multi-model SQL engine provides dedicated data types and functions. It can comprehensively process information and respond to a query for 100,000 "locations and events" in billions of data records within milliseconds, providing a new SQL query pattern based on a 5G + IoT platform. It can be applied to intelligent map navigation, intelligent logistics, IoV tracking, city brain, and other scenarios
Hot and Cold Data Separation
As businesses grow, the data volumes of core business tables in the database increase. In the OLTP-oriented database architecture of Oracle, table expansion frequently occurs, affecting the business query efficiency. The cloud-native oss_fdw plug-in separates hot data and cold data for storage. Based on the plug-in, cold data is stored in Object Storage Service (OSS), enabling unlimited storage of massive cold data. Online Transaction Processing (OLTP) and Online Analytical Processing (OLAP) tunnels can be connected to transmit business data to the data warehouse. This enables report queries and online and offline big data analysis, providing decision-making support for enterprise customers.
