At a certain point in the lifetime of your applications, it might make sense to create an application to replace the old one. Cost savings, maintenance effort, and features available in new apps can help you determine if it's better to build a new application or modify an existing one.

Consider building a new application for the following reasons:
  • The existing application is outdated and doesn't run well on newer hardware.
  • Building a new application would produce cost savings over updating and maintaining the existing application.
  • The existing application doesn't fundamentally meet your business needs.
  • The existing application's features can easily transfer to a new application.
  • Updating the existing application would cause significant disruptions to your UI and workflow because the existing application does not support the features you want to add.
  • A new application would resonate with more users through an updated UI, more features, and ease of use than the existing application.
  • Building a new application would be a quicker and easier process on low-code platforms like App Engine Studio (AES) than maintaining the existing application.
