Migration

Your Blue Prism bots are running fine on the stable systems they were built on, but the business keeps changing. A new UI, a renamed field, or a business rule tweak breaks a bot that used to run unattended for months. You are stuck on a treadmill of fixes and retests. Meanwhile, many business processes still sit on paper or in spreadsheets because building a bot takes months and the next change is already in the queue.

Why RPA breaks here

Traditional RPA like Blue Prism relies on selectors, XPath, and object IDs. These are brittle. When the application UI changes, the selector no longer matches and the bot fails. Automation teams report that a single UI update can break 10 to 30 percent of bots, forcing a rebuild and revalidation. The cost is not just engineering time. Teams spend 20 to 40 percent of their automation budget on maintenance and rework, not on new value.

What changes with computer use agents

  • Survives UI changes because the agent sees the screen and acts like a human
  • No brittle selectors or object repositories to maintain
  • Recovers from exceptions instead of halting: it reads the error and tries another path
  • Follows the SOP as written, without a flowchart bot to build
  • Works across any app, including legacy systems, Citrix, and virtualized desktops

Computer use agents let you automate the long tail of changing processes without rebuilding every time the UI shifts.

How to move without the risk

Start with a single high-pain process that is UI-heavy and exception-prone. Document the current steps in plain English as a standard operating procedure. Run a pilot with a computer use agent to see how it handles the process end-to-end. Measure the time saved, the number of exceptions caught, and the stability over a few weeks. Use those results to prove value to stakeholders and justify a broader rollout. Reserve traditional RPA for stable, high-volume backend tasks that benefit from speed and predictability. Meanwhile, expand the agent use case to other processes that sit on paper or are too complex for brittle bots.

A practical migration playbook

  • Identify one process with frequent UI changes and many edge cases
  • Write the steps as a plain-English SOP
  • Run a pilot with a computer use agent and compare to the current manual or RPA approach
  • Measure uptime, exception handling, and time to complete
  • Scale to a few more processes while keeping RPA for stable, high-volume work

The durable path forward

Moving from Blue Prism to computer use agents is not about replacing everything at once. It is about replacing the brittle, maintenance-heavy work with agents that adapt to change. You can keep the bots that run reliably on stable systems while using agents for the processes that are too complex, too variable, or still manual. This hybrid approach lets you reduce maintenance spend and unlock automation on processes that were previously out of scope.
