A Comprehensive Guide to Migration Testing of Data?

Migration Testing

Movement Testing is a check cycle of relocation of the inheritance framework to the new framework with insignificant disturbance/margin time, with information respectability and no deficiency of information, while guaranteeing that every one of the predetermined utilitarian and non-useful parts of the application is met post-movement. As we probably are aware, the application relocation to another framework could be in light of multiple factors, framework solidification, old innovation, enhancement, or some other reasons. Thus to guarantee a smooth relocation of the live framework by wiping out those imperfections, it is fundamental to complete Migration Testing in the Lab.

Migration Testing Techniques

  • Column Count and Data Comparison at the Database Level

This approach requires SQL information as the need might arise to get ready contents in light of the planning report and necessities. The QA group needs to make SQL questions that cover each part of a table as well as characterized the scope. They then think about the number of records and information moved relating to each ascribe of the heritage data set with the objective data set. The advantage of this strategy is that the QA group can refresh the SQL scripts at whatever point they are required.

Information correlation should likewise be possible by utilizing Macros. In this strategy, the information from the source as well as the target data set is extricated into a successful accounting sheet and afterward looked at. Nonetheless, this approach isn’t good while managing an enormous amount of information.

  • UI Verification of Migrated Data

This method is significant in information relocation testing since it checks how the moved information will show in an application to an end client. Every one of the relocated information ought to hold its worth and configuration except if it is explicitly referenced not to do as such. In this method, the information from the heritage application/data set is contrasted with the objective application to check whether the information is populated in wanted fields. QA designers ought to constantly take the dataset that has values in every one of the fields and check a couple of records from all relocated data set tables. Mechanization contents can likewise be utilized with test information from a heritage framework and approved against target applications.

  • Execution of Data Validation Scripts

It is another self-prearranged approach where the exactness and nature of relocated information are checked. Two distinct applications will have various mappings on the mapping table. At the UI level, it isn’t possible to take a look at whether every one of the information is moved by the necessity or target application or not. Subsequently, in information movement testing, make information approval SQL scripts that will confirm assuming any relocated information exists in the objective framework that is against the application’s base way of behaving or pattern. For instance, two clients can’t have the equivalent username. Consequently, a SQL question can be composed to approve this in the objective data set.

Utilize this testing procedure after contrasting the information between the heritage data set and target data set. Consequently, all disparities found while executing information approval scripts are not genuine bugs but rather contain the information that needs cleanup and ought to be sent back to the client for their criticism. This strategy likewise ensures that the information is finished where no invalid or clear qualities exist for required fields.

  • Approval Testing at Application Level

Approval testing concludes regardless of whether the framework capabilities as it was planned. An application with relocated information ought to work equivalent to it was working before the information movement and ought to meet all predetermined business necessities. This method checks the strength of the application and guarantees smooth running with moved information. In this, an analyzer confirms an application’s center functionalities utilizing relocated information. Information is an evaluative part of any business. A little miss in the check of moved information could bring about a gamble of disappointment at creation. To keep away from such dangers, the above information movement testing procedures can help an analyzer in finding any disparities in the relocated information. It prompts quality testing and a superior client experience.

Migration Types

  • Application Migration

For this situation, a whole application should be moved from one stage to another one. For instance, relocating ASP.Net to Windows Azure or moving an application to the cloud. Testing ought to include: distinguishing prerequisites and extent of testing, testing the stream in the heritage application and difference it from the enhanced one, and – if essential – testing the new stream.

  • Server Migration

For this situation, the server information and the design are relocated to another server. Relocating HP Box to IBM Box could be a genuine model. While performing data migration testing, specialists ought to guarantee consistence with the objective server and test information taken care of. It is essential to ensure that there is no information defilement.

  • Data set Migration

For this situation, every one of the information in an application’s data set is moved to another data set. For the movement to find true success, the application needs to be steady and the information to be substantial. RDBMS to another RDBMS or MongoDB could be two relocation models.

  • Operating system Migration

This is likely the most confounded sort of relocation. At the point when an application should be moved from a working framework to another one, similarity chances emerge and a huge number (for example interface, arrangement, and so on) could require re-planning. Here are a few models: Windows to Linux, movement to Cloud-based VMs, or relocating to SaaS.
