What is understood by legacy systems?

Legacy systems are older IT systems, applications, or software that have been in use for many years and no longer comply with current technological standards. These systems often use outdated programming languages, databases, or operating systems and are often difficult to maintain and expand.

Why is the modernization of old systems important?

The modernization of legacy systems is important to keep up with technological advancements, improve efficiency and security, and increase flexibility. Outdated systems can incur high costs, as their maintenance and support are often labor-intensive. Additionally, the potential for integrations, automated processes, and user-friendliness is often severely limited.

How long does a typical legacy modernization take?

The duration of a legacy modernization depends on the complexity of the system, the approaches applied, and the available resources.
There is no set timeframe that applies to all legacy modernization projects, as they can vary greatly based on a number of factors.

Can operations be maintained during the modernization process?

Yes, in most cases, it is possible to maintain operations of the system during the modernization process. Generally, this depends on the chosen approach. However, depending on the modernization approach, temporary interruptions or restricted functionalities may occur.
Good planning and communication with affected users are essential to make the transition as smooth as possible.

What costs are associated with legacy modernization?

Legacy modernization costs vary depending on the scope of the project and the methods used. If you want to carry out your legacy modernization on your own, the costs can be calculated from the following factors, among others: Development and implementation costs, infrastructure costs, training costs, licensing fees and software costs, and external consulting expenses, if required. Keep in mind that if you carry out your modernization projects yourself, unforeseen problems can arise that can quickly cause your costs to skyrocket – especially if there is no careful planning, resource allocation and monitoring, and expert knowledge is lacking.

A professional IT service provider like Alfa IT Outsourcing, who understands your company’s culture and goals, will implement your modernization processes efficiently and successfully, making your cost analysis and budget planning much more transparent and streamlined.
