Migrations of complex databases need adequate test

Cost savings, consolidation, standardization, operational efficiency, productivity, new technologies, etc. There can be many reasons that lead most organizations to transfer their databases to another product of a database management system (DBMS). But most database migrations can be very complex and time-consuming, since each database has its own characteristics. It is quite difficult for companies to switch from one DBMS to another. Migration projects can also take several months and carry huge upfront costs, forcing companies to delay or cancel their migration plans.

Stay ahead of the competitors

But for companies that understand that migration is very important to stay ahead of the competition, they need to develop a migration strategy to ensure careful planning, qualified resources, proper use of tools and rigorous 먹튀 testing to succeed. The main objective of the migration project is to transfer data from the inherited system of origin to the new destination system, and the problem is the difference in the structures of two separate databases. The database migration test will ensure the correct and efficient operation of applications designed to transfer legacy data to new platforms.

Companies must take into account the commercial risks associated with the transfer of data between the two systems. Several aspects must be verified, such as the physical and logical architecture of the database, security, functionality and performance. Security mechanisms can be completely different in two separate databases. Therefore, security must be guaranteed so that only authorized users have access to the database. In addition, it must be ensured that the transferred data is correct and complete, and must also be verified after the migration is complete.

Levels of database compatibility

Despite the fact that there are many levels of database compatibility that initially support their own extensions to the DBMS, which would increase the speed of migration, the tests, as a rule, remain the same and remain very important. Quality control and testing professionals must participate from the beginning of the data transfer project, since even the type of inherited database can influence the way data is transferred. From the analysis stage, a test strategy must be developed and detailed test cases developed, constantly improving on the project. In addition to testing applications, tests for the performance and scalability of the application and database must be provided for compliance with the new levels with the requirements of the company. In general, effective tests of database migration using a combination of automation and manual methodologies can provide performance, reliability, scalability and availability.

You finally thought you were done.

It was impossible to convince him to go through this again without an emergency. Then, he backed up the intact database. If you are lucky to have storage available, of course. And it goes without saying that, after two weeks, the database model has changed. Not much, but enough.

Migration can be risky and, if not organized, cannot achieve the expected objectives of business and technology. Quality assurance (QA) and the necessary tests before moving on to production is the key to a successful migration.
