FAQs

01/

Can we modernize legacy applications without operational downtime?

While legacy application modernization services focus on updating outdated software and IT infrastructure to become more agile, efficient, and secure, a key consideration is minimizing disruption. This includes various strategies to smoothly transform existing systems into more agile, efficient, scalable, and secure platforms. The goal of legacy app modernization services is to address limitations, improve performance, reduce costs, and enable innovation.

We achieve this through careful planning and strategies tailored to your specific system, such as phased rollouts or parallel operations. At NIX, we provide legacy app modernization services to help businesses transition their legacy applications towards modern architectures, improving performance, reducing costs, and enabling innovation.

02/

What are the timelines and costs of upgrading the application?

At NIX, we understand that the timeline and cost of application modernization services are key business considerations. Our approach involves a detailed evaluation of your organization’s specific requirements and growth objectives to develop application modernization solutions that deliver tangible business results and a clear return on investment.

Modernization timelines depend on the scope of updates, application scale, complexity of new capabilities, and necessary testing for business continuity. To ensure your application modernization efforts directly support your long-term business strategy, our application modernization consulting services focus on the strategic allocation of resources, selection of optimal technologies, ongoing operational support, and aligned infrastructure investments, including cloud options.

03/

What challenges does application modernization entail?

A key challenge in application modernization services stems from the accumulated technical debt within legacy applications, often manifesting as complicated codebases and outdated technological frameworks. At NIX, we expertly address this through strategic code refactoring and bridging potential skill gaps within development teams to effectively leverage modern technologies, especially in application modernization services from legacy to cloud. Moreover, ensuring data integrity, achieving regulatory compliance, and proactively mitigating security vulnerabilities across the evolving technology landscape are critical considerations demanding expert oversight.

04/

What is the difference between application modernization and digital transformation?

Legacy software modernization services mainly focus on updating and enhancing existing applications. This often involves moving to the cloud and incorporating modern development practices to extend the life and functionality of legacy applications.

Digital transformation, on the other hand, is a broader approach that involves revisiting business models, reinventing customer experiences, and embracing new technologies to transform and automate business processes. Therefore, app modernization services are a key component within the larger scope of digital transformation.

05/

How can I assess the need for application modernization for my business?

You can assess the need for application modernization services by identifying key indicators—such as frequent problems like crashes or slow performance, high maintenance costs for your legacy application, security risks and compliance issues, inability to scale with your business growth, and negative user feedback. To evaluate further, compare the cost of maintaining your old system versus the investment in app modernization services, check if your current applications support your strategic business goals, and analyze the extent of technical debt hindering your progress.

At NIX, we provide application modernization consulting and can help you evaluate your needs, provide expert plans for enhancements, and offer technical expertise to start your modernization journey.

06/

What are the business risks of not modernizing a legacy app?

The business risks of not modernizing a legacy app are substantial, encompassing greater security vulnerabilities, inefficient operations that drain resources, a subpar user experience impacting productivity and customer satisfaction, and restricted scalability limiting growth. You can also encounter increasing maintenance expenses and challenges in meeting compliance standards, creating significant operational and financial strains. Contact NIX for application modernization consulting services, aligned with your specific business context, to unlock the strategic benefits of legacy application modernization.

07/

Can you embed AI into an application?

Yes, NIX can expertly embed AI, including generative AI, into your applications. We leverage advanced predictive analytics for strategic planning, real-time insights powered by machine learning, and AI agents to enhance customer experiences. Our specialization extends to applying large language models (LLMs) for human-like chatbot conversations and employing natural language processing (NLP) to unlock valuable intelligence from textual data. Furthermore, we can integrate generative AI capabilities to create personalized content and enhance various application features.
