Our solution to tackle obsolescence


Brief description of the solution

PERCALL has developed SOLINGS, a web-based solution that can replace legacy systems without harming stored data and with uninterrupted access. SOLINGS combines multi-connectivity to existing data sources with aggregation technologies and a modern and intuitive user interface in order to facilitate the adoption and ensuring the smooth transfer of skills, from one generation of employees to another.

SOLINGS can be deployed step by step into your the Information Systems, one functionality after another including new features such as Augmented Reality ensuring continuity of services. The project will create a new standard for legacy retirement and replacement. This is a premiere.

Concepts and issues

Industrial data must live at least 50 years. However, this is twice the lifespan of the IT systems that handle them.
The obsolescence of legacy systems is a major challenge that can cause serious risks to business and industries worldwide.


With obsolescence, software licenses either disappear or turn incompatible with the new standards (Hardware based 32 or 64bits, Operating Systems,…) and the hardware cannot run anymore. Data must migrate and equipment must be replaced. This is a costly, complex and risky process, that can cause a temporary stop to the production and massive investment in new hard/software that only expert people will be then able to handle.


If the company cannot afford the switch to a most recent version of Information system, it buys old components and expensive extension of warranty to continue to use the old systems.

This is also a counter-productive move that goes against the digital transformation of the Industry.

The old systems become legacy systems and hinder the access to critical data in major industries.
This has consequences:


Bugs and compatibility issues are multiplying. Critical data can become unavailable.

The repair is costly with uncertain outcomes.

  • Norms are evolving fast, whilst software are not: for instance, an Industrial will fail to exchange data package directly through Secured Internet Connection with its supplier, due to the limitation of an hardware unable to use an External Encrypted Hard Drive (EEHD) with code to transfer via a secure courier. Another example: the limitation of an INTEGER had been reached compared to the hardware server that was blocked in 32 bits (2 147 483 647) knowing that on 64 bits hardware server the INTEGER limit is 9 223 372 036 854 775 807. The use of this application was blocked during three weeks.
  • In spite of the intervention of expert IT repair by the editor, the compatibility issues will persist over time.
  • Therefore, maintaining legacy systems up and running is unavoidably pointless. For instance, in the aircraft industry, it will cost around 10M€ per year by program for an aircraft manufacturer to continue to use the old systems.

 The risk is to Stop the production caused by the lack of access to critical data. These incidents have heavy impacts on the business. About 25% of the companies that experienced a shutdown of their production line last year due to obsolescence of legacy systems, assessed that they lose at least 1 million euro per incident (article Wavestone – Agata KWASNIEWSKA – 2015).


During the migration of data to a more recent IT systems, the continuity of service is jeopardized.
The rehabilitation of the service as it used to be is also uncertain.

  • Even though industries try to make the migration as transparent as possible, the time to train the users to the new systems delays the actual transition.
  • The risk is also high to lose data/information or to generate inconsistency between data during the transition. This is due to the incompatibility of data model from both solutions. 
  • A recent study on the quality of data by Experian Marketing Services, in 2015, shows that 9 out of 10 companies are involved in data migration projects and 85% of them experience significant problems during their implementation.

Therefore, industrials will risk to “waste” their investment in IT: In 2018, 78% of IT budgets were spent solely to maintain obsolescence solutions with no clear improvement of the obsolescence constraints.
How much does this leave to invest in innovation?


The skills gap is getting deeper between employees.
The younger workforce with IT skills find no motivation in working in “old environment”
  • The level of IT expertise required to manage legacy systems is quite high. The new recruits, trained to the most recent technologies and as such, are barely keen to address the legacy challenge.

 It is a critical risk to lose skilled and young workforce. By 2027, more than a third of the workforce of Europe’s major industries will have to be renewed, especially by IT skilled people. In a context, where these IT skills are scarce, this makes the issues of obsolescence of legacy systems even more concerning.



Maintenance &

Maintenance cost can exceed the original development budget in just 5 years after the product release.

Integration &

Failure to comply with industry regulations could potentially lead to millions in penalties.


The estulated average cost of data breach in $4 milion, according to IBM.

Lost Business

The lack of innovation can impact your business’ long term profitability and competitiveness.

Agility and

The average efficiency of some processes can increase up 50% through automation and modernization.

Many industries, for which the integrity of the data is critical, are in a deadlock.
In this context, PERCALL has developed “SOLution of thINGS”, SOLINGS, the first and only solution able to replace the Legacy systems with no migration of data. This means no risk of alteration of data.


SOLINGS is a connected system platform, based on IoT Platform (Internet of Things), that provides a single access point, for all users, to all data for PLM Legacy applications that undergo software obsolescence.

The concept of SOLINGS relies on two intertwined innovations:


A multi-connected solution with direct connection to the old data base of the Legacy systems as the “old” ones by default to ensure smooth transition.


A web-based application with owns modern capacities (in terms of search, display, aggregation and more…) in addition to the same Legacy features as the “old” ones by default to ensure smooth transition.

  • Providing a single access point for all users, to all databases by creating a modern and open interface using the best and most efficient technology bricks on the web.
  • Controlling the security of the data sources from their legacy applications using the ability to connect with the different applications of an information system maintained or not by the Editor. This insures that users cannot modify a data without proper authorization.
  • Enabling a flexible and smooth deployment. The aim is to deploy function-by-function for Business Users to avoid sudden change.
