Testing is crucial during the migration of legacy applications to the cloud in order to avoid any data loss or downtime. So, analyzing and determining which testing strategy to employ while performing a migration is critical. Enterprises must invest quality time and effort to establish a proper migration testing plan. A well-defined migration testing strategy is essential to mitigating the risks involved and delivering a successful migration. This is comprised of three phases: Pre-Migration, In-Migration, and Post-Migration. In this post, we’ll break down what goes into the In-Migration and Post-Migration phases.
Let’s start with the testing types involved in the In-Migration testing phase:
- Configuration Testing — Configuration testing helps in evaluating the immediate or long-term effects of configuration changes on a system’s behavior and performance. It also helps teams find the tech stacks with which the system can work without any flaws or issues while matching its functional requirements.
- Data Validation Testing — Data Validation testing allows you to make sure that the data which you’re dealing with is complete and accurate. For any discrepancy in the report being migrated, the system will display errors that have occurred during the migration process. To receive an accurate report, issues will have to be resolved.
When you perform follow-up tests, Post-Migration testing comes into the picture. This will give a clear idea of the various types of testing that get covered here called Cloud Ready Transition. This phase of testing should include:
- System Integration Testing — SIT, or System Integration Testing, is the process of comprehensive testing performed on software that is composed of many sub-systems. Systems Integration Testing looks into software module dependencies to determine if they are functioning properly and if the data integrity is preserved between distinct modules of the whole system.
- User Acceptance Testing — This is the final phase of any software development lifecycle (SDLC). This process plays an important role, as it validates whether all the business requirements are in sync before the release. Before the software is released in the market, the User Acceptance Test has a wider role to play in ensuring whether all the functional specifications defined by the product owner are present.
- Security Validation — Security validation discovers potential threats that a user could face. It allows an organization to test an attack in their own environment safely and provide them with evidence of whether this attack can be prevented. The process ensures that the security systems satisfy the requirements and the product quality actually meets the client’s needs.
- Report Validation — Validation provides input on whether the product is up to snuff. This process validates the actual and expected output of the software and ensures that the product meets the user’s requirements.
- Business Process Testing — Functional validation, or cloud-ready validation, assesses production readiness of migrated applications. It is fundamental to verify if various aspects of the migrated applications are performing as per SLA requirements. For an effective cloud migration, validate the SaaS/cloud service's functions, and perform end-to-end application function validation.
- Interface Testing — Cloud migration comprises moving data along with managing a range of variables, such as security, authentication, integration, compatibility, testing, and monitoring, over time. All the interfaces and systems, like middleware and databases, are covered while planning for integration testing. Key areas of testing should include real-time/near real-time processing of requests, large dataset file processing, HCM, and ERP cloud adapters.
- Report Validation Testing — Report Validation is critical to identify a pre-conversion validation plan which relies heavily on the review of FBDI load errors as they occur, resulting in a scramble late in the project to review and repair records. This is followed by a disjointed post-migration validation process that involves spot-checking records from the front-end, ad hoc Excel dumps, and a comparison between legacy and cloud reports.
- Security Testing — The objective of the security architecture is to enable you to maintain your security posture when running Oracle E-Business Suite and associated applications in Oracle Cloud. Even though you may be reducing the overhead of building and maintaining data center infrastructure, you still need unparalleled control and transparency over what you’re running in the cloud.
- Regression Testing — End-to-end regression validation should include testing of the configuration, data, and code migrations. Tests should include managed customizations and configurations along with validation across multiple locations.
Our recommendation for shifting left ensures early detection of defects in the developmental stage which ensures quality delivery and zero risks in the testing phases. The varied testing processes take care of individual aspects involved in the detailed validation check. Enterprises planning to migrate to Oracle Cloud should adopt the above testing process to achieve a stable migration that would allow for unhindered business continuity.
