Migrating Legacy Applications for an Advanced Future
Businesses need advanced software solutions to stay competitive in the current economy. These solutions are like packed eatables: Their services will only be valid until a particular period of time, after which these packets need to be replaced with newer releases. Similarly, legacy applications of a business enterprise need to be upgraded regularly as technology is evolving faster than the passage of time.
What are legacy applications and why do businesses use them?
It’s important to comprehend the entire picture at first so that necessary steps can be taken. A legacy application is any application based on older technologies that continues to provide core services to an organization. In short, it is a software program that is outdated or obsolete. Upgrading or migrating the content of legacy applications can be daunting tasks if not performed by subject matter experts.
Such applications were originally built by developers who might no longer maintain them. Further, the current support teams of businesses may not have the necessary depth of knowledge to do so. The long duration and the costs that are falsely believed to be involved in the process also deter businesses from migrating them.
The problem is that not all businesses can afford to spend money on software upgrades continuously. These businesses will use legacy applications as long as they are useful and then drop the plan when these applications become inefficient.
Consequently, businesses land back on square one without any software applications to streamline their activities and improve efficiency in reaching targets. It is strongly recommended to avoid this scenario, as commercial enterprises worldwide are becoming automated and we are entering another industrial revolution.
What are common obstacles?
Legacy Transformation: This is about retaining and extending the value of the legacy investment through migration to new platforms; however, legacy applications are frequently large and difficult to modify. Transforming them could involve re-engineering an organization's business processes as well.
Revitalizing Legacy Code: The legacy codes need to be changed regularly and tests need to be performed on each change. This is necessary to ensure that the new code works and doesn’t negatively affect the existing features. These changes will take time and will not enable businesses to make the changes as quickly as preferred.
Living with Legacy Applications: Such applications will continue to exist as they are. Businesses cannot modify their features or add new ones according to the change in trends. Modernizing these legacy applications will need a larger level of investment with which a business can develop a new app.
Avoiding Legacy Pitfalls: In times of mergers and acquisitions, businesses will face a large issue with their legacy applications. The versions of software used in these businesses may be totally different and incompatible with each other. The consequence will be a big drop in productivity and business management.
