If you need an RPA tool that works well with legacy systems, the best choice depends on the type of legacy app you mean:
Good options for legacy systems
- UiPath — very strong for mainframe, Citrix, terminal emulators, Java apps, and older desktop systems.
- Automation Anywhere — good support for desktop automation and virtual environments.
- Blue Prism — solid for enterprise legacy app automation, especially stable back-office processes.
- Microsoft Power Automate Desktop — decent for simpler legacy desktop automation, especially if you’re already in the Microsoft ecosystem.
What to look for
For legacy systems, prioritize tools that support:
- UI-based automation for apps without APIs
- Citrix / VDI automation
- Mainframe / terminal emulation
- OCR / computer vision
- Desktop automation for Windows forms, Java, and older web apps
My quick recommendation
- If you want the most capable overall: UiPath
- If you want enterprise governance and stability: Blue Prism
- If you want Microsoft-native and lower complexity: Power Automate Desktop
If you tell me what kind of legacy system you have—like mainframe, Citrix, SAP GUI, old Windows app, or terminal emulator—I can recommend the best tool more precisely.
