Legacy Delphi versions served us well, but outdated components and 32-bit limitations can hold your business back. Our calculator analyzes your current environment to estimate the effort required for a seamless upgrade.
Answer a few technical questions about your project to receive a high-level migration estimate and discover the fastest path to a modern, secure, and scalable application.
What is the current Delphi version?
Legacy (Delphi 7 or older)
Pre-Unicode (Delphi 2005 - 2007)
Early XE (XE - XE8)
Modern (Delphi 10 - 13)
Approximately how many lines of code (LOC) make up your project?
Small (< 250,000 LOC)
Medium (250,000 – 1,000,000 LOC)
Large (1,000,000 – 2,500,000 LOC)
Enterprise (> 2,500,000 LOC)
I'm not sure
(Exclude 3rd-party libraries and focus on your custom source code)
What are the number of units (.pas files)?
< 50 units (Small)
50 - 250 units (Medium)
> 250 units (Large)

What is the status of your third-party components?
Ready to go: all our components have modern versions available for Delphi 12+
Partially missing: some components are discontinued or we are missing the original source code
Custom-heavy: We rely heavily on internally built or highly customized components
I don't know
(e.g., DevExpress, TMS, Raize)
Which database engine or framework does the application currently use to connect to data?
BDE (Borland Database Engine)
dbExpress
FireDac
ADO
Other (e.g., UniDAC, Zeos or direct DLL calls)

How does your application handle strings and character encoding?
Modern (Unicode): The app is already Unicode-compliant (common if built in Delphi 2009 or newer)
Mixed: We have a mix of modern code and old logic that handles specific character sets
Legacy (Non-Unicode): The app makes heavy use of AnsiString, PChar, or legacy Windows API calls for text (common in Delphi 7)
I don't know
How would you describe the primary architecture of the software?
Monolithic (Client-Server): A standard desktop app connecting directly to a database
DataSnap: Uses Embarcadero's specific multi-tier middle-man technology
Multi-tier (REST/SOAP): A modern approach using web services or microservices
COM/ActiveX Dependent: The app relies heavily on external Windows components or OLE automation

Your application is in great shape. Based on your answers it's going to be a low-complexity project.
But, even for low-complexity projects, manual updates can be tedious. We utilize the GDK Duster, our proprietary migration tool, to automate the repetitive parts of the upgrade. This ensures your code remains clean and free of "upgrade artifacts" while significantly shortening the testing phase.
Shall we talk Delphi? To confirm a timeline and discuss how we can execute this move with zero downtime, we advise scheduling a free consultation.
Upgrading your application is a
medium-complexity project
. Your project has a solid foundation, but contains elements that require expert attention. Upgrading your Delphi-project will significantly improve the performance and maintainability of your software.
To handle the heavy lifting, we deploy the GDK Duster. This specialized tool is designed to scan your entire codebase and automatically replace deprecated components and logic with their modern equivalents. By using GDK Duster, we reduce the "human error" factor and cut down the migration timeline by up to 40% compared to traditional manual methods.
Shall we talk Delphi? We recommend a free consultation to review your specific third-party dependencies and create a tailored roadmap.
Upgrading your application is a
high-complexity project
. Your application is a true "workhorse" with a deep history. The combination of legacy architectures (like the BDE), older Delphi versions, and complex integrations makes this a high-stakes migration. However, this is also where the biggest gains in security and scalability are found.
High-complexity migrations are where the GDK Duster shines. Instead of your team spending months manually refactoring thousands of lines of code, our tool automates the bulk of the conversion. This allows our senior developers to focus on the high-level architectural improvements and custom logic, ensuring your "VCL goldmine" is successfully transformed into a modern enterprise solution.
Given the complexity of your environment, we highly advise planning a free consultation. We can demonstrate how GDK Duster handles complex legacy code and provide a more granular breakdown of the project phases.
