App Modernization: What is the Best Approach?

The most important three Rs are no longer Reading, Writing, and ‘rithmatic. In the Information Age, they’re the Rewrite, Replace, and Reuse of legacy application modernization. Apps are increasingly the backbone of nearly all modern core business functions, and keeping them up-to-date is essential for remaining competitive. Developers must decide how to retool or maintain them efficiently.

Fortunately, intuitive development makes complete replacement unnecessary unless you’re migrating to a completely different platform that isn’t supported by your current technology. Performing thorough app evaluation and risk assessment are required to determine which approach will best suit the needs of your company.

Evaluate the App

The first step, of course, is to evaluate your apps, as well as the OS and server, to determine which can be modernized, and what aspects, and which need to be replaced. You should look at:

  • The activities being performed
  • Which elements of code are too restrictive for emerging requirements
  • Constraints in development that need specialized skills
  • Accessibility, performance and flexibility of the database

Evaluate Legacy Data Migration Significance

How is your essential data being processed, moved and stored, and how can this be improved by modernization? Prioritize data processing from critical to lowest priority, and work to optimize in that order.

Assess Software Security Threat Levels

What are the current security holes and weaknesses, and how can they be eliminated by modernization rather than simply patched? Prioritize the weakness and consider measures to address them.

Assess Risk Mitigation Capabilities

Look at vulnerabilities in your overall system and app deployment, and how these vulnerabilities will affect your enterprise if breached. Also consider how one breach could exploit other, lesser vulnerabilities, imposing a greater risk to the system overall.

Protect App From Data Loss

Enhance data loss prevention measures before, during and after migration. This can be taken care of with off-site or cloud storage backup, by using stronger passwords and with more specialized data encryption.

Once you’ve evaluated your legacy applications, you’ll be able to use the results of the assessment to formulate your approach.

If you don’t have the time or the tech know-how to update your apps, companies like AveriSource are the way to go. Businesses that specialize in app development are on top of the latest trends and best practices. Outsourcing this vital component of your business is a smart investment in future relevance.
