What is the code migration?
The code migration is to move the programming code from one system to another. There are three different levels of code migration with increasing complexity, costs and risk. Simple migration includes movement from the tongue to a newer version. The second, more complicated level of migration includes a transition to another programming language. Migration to a brand new platform or operating system is the most complex type of migration.
The first type of code migration is a simple movement from one version of the tongue to a newer but syntactically different version. This is the simplest route of code migration, because the basic structure and most programming constructs usually do not change. In many cases, the old code would really work, but new and improved routines or modularization can be improved by reworking the code to suit the nature of the new language. Therefore, the code migration would lead to greater efficiency in implementation.
The second level of the Migration code would migrate into a completely different programming language. This could be caused by transfer to the newon the software system or implementation of another management system of relational databases (RDMS). This type of code migration often requires programmers to learn a brand new language, or new programmers would be brought to help with migration. In this case, the entire program must be rewritten from the ground up. Although most constructs are likely to exist in both languages, accurate syntax is usually quite different.
The most complex example of code migration is migration on a brand new platform and/or operating system (OS). It not only changes the programming language, but also the machine code behind the language. While most modern programming languages protect the programmer from this low level code, the axis and how it works, it is necessary to produce a code that is effective and is done as expected.
Regardless of the type of code migration, access should be the same. A team of migration or programmer should each module,Divide the function and sub-authobil into the program's purpose and development diagram. This is the reverse engineering of the original software development (SDLC). Once these modules and functions are mapped at a high level, they can be rewritten and tested in a compartment in a new language. Like any advanced computer programming project, the key to successful code migration is the correct planning and documentation.
