Salesforce continues to evolve its AI ecosystem, and one of the most significant changes introduced in the Summer ’26 release is the transition from the Legacy Agentforce Builder to the new Agentforce Builder in Agentforce Studio. Starting the week of 13 July 2026, organizations can no longer create new AI agents using the Legacy Builder. Instead, all new agents must be built in the modern Agentforce Studio experience. Existing agents remain fully supported, but Salesforce has made it clear that future innovation will be centered around the new builder.
Meet the New Agentforce Builder
The new Agentforce Builder, available within Agentforce Studio, is Salesforce’s next-generation environment for designing, configuring, testing, and managing AI agents. Built with modern development practices in mind, it delivers a streamlined experience while introducing advanced capabilities such as Agent Script, visual debugging, intelligent previews, and AI-assisted development.
Unlike the legacy experience, the new builder is designed to help administrators and developers build enterprise-ready AI agents faster while maintaining greater control over workflows, logic, and governance. It also provides a unified interface where organizations can create custom agents, leverage templates, and optimize agent performance without switching between multiple tools. Salesforce has positioned this builder as the foundation for all future Agentforce enhancements.
What Changed?
The most important change affects only the creation of new AI agents. The New Agent button has been removed from the Legacy Agentforce Builder, meaning every new implementation must now begin in Agentforce Studio.
The good news is that organizations using the legacy builder do not need to worry about their existing deployments. Legacy agents continue to function normally, and administrators can still edit, activate, deactivate, version, and manage them. This ensures business continuity while giving teams enough time to plan their migration strategy.
To simplify the transition, Salesforce also introduced a one-click upgrade process that converts legacy agents into the new Agentforce Builder. During migration, important components such as subagents, actions, system messages, settings, data, and connections are automatically converted into Agent Script, significantly reducing manual effort.
What Should You Do Next?
If your organization currently relies on legacy Agentforce implementations, now is the ideal time to begin planning your migration. Moving to the new Agentforce Builder not only aligns your implementation with Salesforce’s latest architecture but also ensures access to future AI innovations, performance improvements, and platform capabilities.
Salesforce recommends upgrading existing agents whenever possible rather than rebuilding them from scratch. The automated upgrade process preserves your original agent while creating a new version in Agentforce Studio, allowing teams to validate functionality before production deployment. This minimizes risk and accelerates adoption of the new platform.
For all future AI initiatives, organizations should build directly in Agentforce Studio. Adopting the new builder today will help businesses remain scalable, maintainable, and ready for upcoming Salesforce AI enhancements.
Why This Matters for Salesforce Customers
The shift to Agentforce Studio represents more than a simple interface update. It reflects Salesforce’s long-term AI strategy focused on intelligent automation, governance, and enterprise scalability. Businesses adopting the new Agentforce Builder gain access to richer development tools, better debugging capabilities, AI-assisted configuration, and a future-proof architecture designed for increasingly sophisticated autonomous agents.
For Salesforce customers investing in Agentforce, Salesforce AI, AI agent development, CRM automation, and enterprise AI solutions, migrating sooner rather than later will reduce technical debt and ensure compatibility with future platform releases.
