Legacy Migration

With rapid changes in technology and business, IT infrastructure also needs to be cutting edge, in order to optimize operational activities, reduce maintenance costs, and fully leverage the latest technologies.
For many businesses, IT support must keep pace with the growth of the market. There are times when a legacy system can no longer be upgraded to meet the requirements of the business, necessitating a switch to a different platform.

A smooth platform migration will retain all existing business processes, ensuring consistency with other the modules in the infrastructure, while at the same time providing the potential to add a specific number of new functions, incorporate the use of newest technologies (such as those for mobility and the IoT), and vastly extend the ability to upgrade in the future.

This process can involve the rebuilding of an aged module using a newer language or relocating an old system service to a new type of server. There are also cases of companies who want to move their operations from a public cloud to their in-house cloud.

Three to four brief points regarding benefits
– Reduce costs of maintenance
– Improve capability and speed of service
– Enable flexibility and ability to incorporate the newest technology
– Enhance security and eliminate vulnerabilities

Challenges
– Migration involves large up-front costs (management overheads)
– Migration that does not hinder the running of the business

Examples of usage
I) Manufacturing company built their inventory management system many years ago in the 1990s. The system was upgraded many times as the company expanded to cover a much wider network of customers. The company now wants to further expand its sales activities by building a new system that can support more analytics features. They also want the system to assist their salesforce through the use of a smartphone application.
II) An import-export company started their business a few years ago and decided to use a CRM cloud solution provided by a public vendor. However, because their business has grown so quickly over the last few years, they now have a need for smarter forecasts and data interpretation, two areas which the cloud vendor cannot support. They finally decided to internalize the CRM system.


What we can do

Combining our expertise in different systems and languages with our knowledge of the latest best-practices on the market, we first offer consulting on the possibilities of transformation options. This approach enables customers to see what options are available and how much they need to allocate for their budget.

The process of migration involves many different stakeholders in the business, and thus it must be performed without causing any disruptions to users (customers or different businesses in the enterprise). A migration project is normally divided into multiple phases, with several different routes for achieving the final result. With different options available, customers can decide which route best fits the operations currently needed for their essential business operations and future strategy.

We will then work together with customers drafting a migration plan. We design the general technical specifications as well as business requirements, and then ensure development produces a final delivery of the best quality.

Our approach

We normally carry out migration projects in multiple phases:
Consultation -> Analysis -> Migration

Consultation
To understand the scope of the project and confirm which items of data are available in the system to be migrated, we conduct analysis and show customers the results. After running diagnosis on aspects such as existing programs, databases, and files, we export a few reports that containing general information, diagrams, flowcharts, and other items. The diagnosis results also help us confirm whether there are any missing items of data or inappropriate data items in the legacy system that may pose obstacles to migration.

Analysis
Using the diagnosis results and working to meet the customer’s needs for transformation, we analyze both the existing system and the new system. Just like the old system, the new system is strictly required to work stably while retaining the added advantages of newer technologies. Excellent analysis ensures smooth migration in the later phases.

Migration
This is the actual phase in which migration is performed. Options such as manual migration or automatic migration using a parser are available to fit the characteristics of the old and new system as well as the size of the project. No matter the option, we provide a guarantee for the testing and maintenance after migration.
