The tech-savvy consumers of today demand advanced and innovative services. This forces organizations to undergo a digital transformation of their legacy apps and systems. Hence, in your digital transformation strategies, it is essential for you to include a plan for modernizing legacy apps.

The legacy app modernization process requires to be more than just replacing or updating outdated technologies. Modernization of legacy apps includes re-engineering, re-imagining, re-hosting and transforming of older apps into newer, modern apps. But before initiating the process of app modernization, you must consider a few important factors.

Let’s take a look at the top six considerations before modernizing legacy applications

1. Integration and compliance

Before modernizing legacy apps, you must look into two aspects – integration and compliance. With legacy apps, you may have to depend on third-party APIs such as user verification, geo-location and data transfer. Modernized apps have built-in integration functionality. However, before modernizing legacy software, you need to ascertain that your apps will be compatible with third-party tools. You also need to ensure that your modern apps will not face any compliance issues.

2. Expenditure review

Legacy app modernization is not an easy task. So, it becomes essential to perform an in-depth analysis of the expenditure. It will help you to ensure that your legacy app modernization process will be profitable for you in future or not. You will need to assess the costs of modernizing your legacy apps and perform the following cost analysis:

Maintenance cost analysis: Estimate infrastructure maintenance costs and calculate maintenance spendings by Constructive Cost Model (COCOMO).

ROI analysis: Calculate the Return On Investment (ROI) to assess your company’s current situation and make appropriate decisions.

Infrastructure cost analysis: Evaluate and calculate the IT infrastructure costs. It will help you to outline how much to spend on the infrastructure.

3. Risk factors

As a business, it is vital for you to consider the risk factors associated with app modernization. In the case of modernizing multiple legacy apps together, you should assess the time required to modernize each app individually. Also, when you have countless lines of code, you should handle the code with extra care. Apart from these, you also need to take into consideration the operational risks that arise during modernization.

4. Existing budgetary resources

For successful app modernization, it is significant for you to have a well-thought-out fiscal plan in action. You need to question yourself – what are the budgetary constraints that you must consider before modernizing legacy apps? The bottom line is your budget must have sufficient funds to allocate for legacy app modernization.

5. Time optimization

Modernizing legacy apps require time and patience. The app modernization process varies for every organization, and so does the time required for modernization. But for any organization, it is crucial to have enough time to implement the modernization strategy. App modernization does not happen in a single moment. It is a journey, which takes time. There is no supposed timeline for it. So, you should take a considerable amount of time for app modernization in order to reap the full benefits out of it.

6. Data management constraints

Since legacy apps encompass a tremendous amount of data, modernizing legacy apps is not an easy undertaking. You need to take a long, hard look at the underlying data first and then use it in an actionable way. To manage data in a better way, you should formulate tactical data governance rules. It will help you to eliminate data silos, making it easier for you to reorganize the data and optimize the storage space.
