Application Migration and Porting - Software Product Development


The Word "Migration" in simple term means shifting or we can say transferring something to a different place. Similarly, if we talk about Migration in terms of application or software it means converting the application to a new platform. It can be explained as importing of legacy data to a new system. Migration is basically used when an application needs to be migrated to new platform or a new system. Needs of Application migration rises with new technologies and the trends in the market.
There are different types of application migrations offered by a software development company:-
* Migration of Operating Systems- Migration of a Windows based application to MAC OS.
* Pre.NET to.NET- It talks about versions, migration of an application developed in previous versions of.NET to latest Versions of.NET.
* Migration of Application Servers.
* JAVA to.NET and.NET to JAVA-it talks about migration of application built in JAVA to.NET or Vice-vice.
* Migration of databases- SQL Server to Oracle etc.
* Migration of Programming language- PHP to.NET etc.
* Migration of mobile platforms. - Migrating of Android apps to iPhone apps or vice -versa.
Now there is a process which most of the companies follow for migration of applications.
* Analysis of existing application.-It is the stage where existing application is analyzed. This analysis consists of Planning, need analysis and risk analysis. It can also be said as Impact study of Migration.
* Identification of the suitable technology- This is the stage where the migration process is prepared by identification of technology, versioning control and library definition.
* Migration of application-This is the stage where actual migration takes place, a system is built and code migration is done.
* Testing of the application -This is the stage which plays a very important role as after the migration stage it's very important to test the application of its working on the new system. This includes testing like unit testing, module testing, integration and system testing and UA testing.
* Porting of the application- At this stage the system is ported and is ready to use.
* Support- It is the warranty Phase which most of the companies offer after the migration of applications for the bugs in the application if any. This support period is defined.
The above stated migration methodology can be customized based on the client requirements and factors like-
* Architecture of the application.
* Nature and size of the application
* Its impact on the business and the priority
* There can be other constraints such as Schedule, cost etc.
Now let's list out some of the benefits of Migration or we can also say the business value that is achieved by application migration.
* It helps in addressing new customers and penetrating in the new market.
* Helps in reducing the complexity and cost of maintenance.
* Release cycle is compressed which improve the time to market.
* Customer satisfaction can be achieved.
* Helps the application to run on the latest platform in the market.
* Architecture becomes scalable and enhanced.
* Integration to other applications becomes simpler and easy.
So we discussed three main things i.e. Migration methodoly, factors which can led to customization of this methodology and how migration can add value to the business. After discussing all these things, the concept of Migration is very much clear.
At the end I would like to conclude by saying the migration is required to make the application accessible on multiple platforms so that it can have benefit from the promises of the latest technologies that are emerging in the market. Migration services are provided by the most of the software product development companies and help the clients to overcome these challenges successfully.

C# Constructor

C# Constructor and its Types – A Detailed Look Definition: In simple terms, Constructor is a special kind of method with class name as method name and gets executed when its (class) object is created. This article will give you a detailed explanation on C# constructors and its types. Now, when we look at the above definition in a broader sense, a constructor is a class method that gets automatically executed whenever class’s object is created or whenever class is initialized.   Consider following bit of code: public class MsDotNetHeaven     {         public MsDotNetHeaven()          {               //A default Constructor          }       //Class members     } In the above snippet, the method MsDotNetHeaven() is called the constructor of class MsDotNetHeaven, also called default constructor. Behind the scenes What happened behind the scenes : whenever you try to create an object of class or initialize a class, then the default constructor will be automatically i

Hiding vs Overriding

As most of you know hiding and overriding are two main features based upon inheritance, which is one of the pillars of the OOP. Using these we can redefine a member of the base class in a derived class. But what are the differences. Let me clear this with a simple example. Start a new web application project with a default web form named "WebForm1" using visual studio. Add 2 class to this project with names "BaseClass" and "DerivedClass". The "DerivedClass" should be a subclass of "BaseClass" (i.e. should define like DerivedClass: BaseClass). Define the following functions in the base class named "BaseClass".  Notice the keyword "virtual".   public   virtual   string  FunctionToOverride() {            return  "This is from base class FunctionToOverride"; } public   string  FunctionToHide() {            return  "This is from base class FunctionToHide"; } Now define th
