As organizations prepare their 2027 budgets, technology leaders are looking for ways to reduce spending without creating new operational or compliance risks. One area that can easily be overlooked is the cost of maintaining legacy applications that are no longer actively used but still need to remain available for historical data, reporting, audits, or regulatory requirements.
A system may no longer support day-to-day business operations, but that doesn’t mean it is free to maintain. Infrastructure, licensing, support, and administration costs can continue year after year simply because the organization still needs access to the data stored inside the application. A recent study from Accenture found that nearly 70% of IT budgets are being used to maintain legacy systems.
For organizations reviewing their technology budgets, decommissioning legacy systems can provide an opportunity to eliminate ongoing costs while preserving the information the business still needs.
The Hidden Cost of Keeping Legacy Systems Alive
Decommissioning a legacy application can seem risky when historical information still has business or compliance value. Financial records may need to be reviewed, auditors may request historical reports, and legal or regulatory requirements may require information to be retained for years after a system is no longer operational.
As a result, organizations often continue running the entire application even when only a small portion of its data is still being accessed. The cost of maintaining the system can become difficult to justify, particularly when multiple legacy applications are being supported across the enterprise.
The costs of “keeping the lights on,” as we often hear, extend far beyond licensing fees. Many legacy applications require specialized technical skills that only a limited number of people possess. As experienced professionals retire, finding qualified resources to maintain these systems becomes increasingly difficult and increasingly expensive.
These costs can include:
- Infrastructure and hosting
- Software licensing and maintenance
- Technical support and administration
- Compliance risks of older technology
- Risks of cybersecurity breaches
These expenses can be easy to overlook during annual planning because the systems may already be considered “retired” from an operational perspective. However, as long as the applications remain running, organizations continue paying to maintain them.
Decommissioning Doesn’t Mean Losing Access to Data
Before we talk about these savings, one thing to make clear is the data access concern with legacy system decommissioning. One of the biggest worries with decommissioning is what happens when someone needs information from the retired system later. Historical data may still be needed years after an application has been shut down, making continued accessibility an important part of any decommissioning strategy.
During the retirement process, organizations still need a way to preserve and access the information that remains important to the business. So, by document legacy decommissioning right, organization preserve historical data access through a separate repository.
Decommissioning tools like Data GUARD by Auritas enables organizations to decommission legacy systems while retaining access to historical data and documents. Instead of continuing to maintain the original application, organizations can move the information into a centralized environment designed for long-term access and retention.
This separates the need to retain the data from the need to maintain the system. The application can be retired while historical information remains available for business reporting, audits, legal requests, and other requirements.
What Should You Calculate Before Decommissioning?
Before deciding whether a legacy system can be retired, organizations need a clear picture of what it actually costs to keep that system operational. Looking only at the application’s license or hosting expense can miss other costs associated with maintaining the environment.
A more complete assessment should consider:
- Infrastructure and storage expenses
- Application maintenance and support
- Internal resources required to administer the system
Once these costs are identified, organizations can compare the expense of continued operation with the cost of preserving the underlying data outside the original application.
This type of assessment can help technology teams identify which systems are consuming budget without providing enough ongoing operational value. It also gives finance and IT teams a more accurate basis for determining which legacy application costs could potentially be removed from future budgets.
Compliance Requirements Don’t End When a System Is Retired
Decommissioning an application does not eliminate an organization’s responsibility to retain information and remain compliant. Historical records may still be subject to regulatory requirements, legal holds, internal retention policies, and future audit requests.
Legacy systems, however, may lack the capabilities needed to address evolving privacy and retention regulations. They may also be more vulnerable to modern cybersecurity threats, creating additional business and financial risk. Noncompliance and security incidents can result in significant penalties, potentially reaching millions of dollars.
Effective legacy system decommissioning addresses these risks by securely migrating historical data to a modern, compliant repository. This allows organizations to retire outdated applications while keeping critical information protected, accessible, and available for audits, legal requests, and regulatory requirements.
Build a Legacy System Decommissioning Roadmap Before 2027
The decommissioning process starts with identifying legacy applications that are no longer needed for day-to-day operations and understanding what is required to retire them. Not every system will have the same requirements, so organizations need to evaluate both the cost of continued operation and the requirements for preserving its data.
Organizations should evaluate:
- Which applications have limited or no active users
- What it costs to keep each application running
- What data and reporting capabilities need to be retained
From there, IT teams can prioritize systems for decommissioning and determine how their historical data will be stored and accessed. This gives organizations a clearer picture of which applications could be retired and how much ongoing spending could potentially be eliminated.
Stop Paying for Systems You No Longer Need
For organizations preparing their 2027 budgets, legacy application decommissioning can be an opportunity to reduce ongoing technology costs. If a system is no longer supporting active business processes and is primarily being maintained for access to historical data, keeping the entire application running may no longer make financial sense. Moving that data into a dedicated environment can allow organizations to retire the original system while keeping the information available when it is needed.
Legacy applications can continue generating costs long after their active use has declined. For organizations planning their 2027 budgets, identifying these systems can uncover opportunities to reduce spending without giving up access to important historical information.
