Migrating from Bullhorn to Atlas: A Practical Guide for Agency Recruiters

Switching ATS platforms can feel like a massive undertaking, especially when you’re moving away from a system as established as Bullhorn. But for many agency recruiters, staying competitive means choosing a platform that truly supports growth, flexibility, and efficiency with your exports.

In this guide, we’ll break down what migrating from Bullhorn really involves, what you can expect during the process, and how to avoid the common pitfalls that slow agencies down when it comes to candidate data. You’ll also learn why many recruiters are choosing Atlas to make their export transition smooth, secure, and surprisingly straightforward.

What is meant by data migration?

Data migration refers to the process of moving all your valuable information, including candidate records, client details, job data, notes, and communications, from one system to another.

In the context of recruitment software data migration, this means transferring everything stored in your existing ATS, like Bullhorn, into a new platform without losing important details or interrupting your team’s workflow. Done right, it ensures a seamless export transition, so your recruiters can keep placing candidates without missing a beat.

Key takeaway: Recruitment software data migration is about moving all your critical data exports safely and accurately, so your business doesn’t skip a beat.

How do you do a data migration?

When migrating from Bullhorn, the goal is to move all your recruitment data accurately and securely to your new ATS without disrupting day-to-day operations. A successful ATS migration starts with a clear plan and an understanding of what data matters most to your agency.

Here’s how agency recruiters like yourself can approach it if you’re interested in migrating:

• Audit your data: Identify what you need to export — active candidates and users, historical placements, client data, and communication history.
• Clean your records: Remove duplicates and outdated information to avoid cluttering your new system.
• Map your data: Work with a new ATS provider like Atlas – the Recruitment Platform to ensure your Bullhorn fields match the structure of the new platform, so nothing gets lost or misaligned.
• Test and validate: Run export test migrations to catch any errors before going live, and involve your team in checking data accuracy.
• Plan your go-live: Schedule the final switch when disruption will be minimal, and prepare your team with the right training.

When done properly, ATS migration doesn’t have to be stressful. For example, with the right partner, you can be confident that your recruitment software data migration will be smooth, secure, and set up for long-term success.

Why should I migrate my data from Bullhorn?

Recruit with a modern, user-friendly interface that raises your team’s productivity

One of the biggest challenges with legacy ATS solutions like Bullhorn is that they weren’t originally designed for the fast-paced, modern ways recruiters work today. By moving to a new ATS, you gain access to a clean, intuitive interface that supports faster, more seamless workflows.

A user-friendly design means your team can spend less time navigating complex systems and more time building relationships with candidates and clients. For agency recruiters, this translates to increased productivity, quicker placements, and a stronger overall experience.

Create faster, more flexible workflows tailored to your agency’s standards

Legacy ATS often force recruiters to work within rigid, one-size-fits-all processes. By migrating from Bullhorn to a modern AI-powered ATS, you gain the freedom to design workflows that match exactly how your agency operates,  whether that means custom pipelines, automated task reminders, or tailored approval steps.

This flexibility empowers your team to respond faster to clients and candidates, adapt quickly to changing priorities, and maintain consistency across the business. In the end, it’s not just about saving time. It’s about giving recruiters the tools to work smarter and deliver a standout experience every step of the way.

Enhance your automation and reliance on agentic AI to reduce admin

Traditional ATS platforms weren’t built with true AI automation at their core. They often rely on add-ons or limited integrations that still leave recruiters stuck in manual tasks. By switching from Bullhorn to a modern solution like Atlas, which is designed from the ground up with AI agents in mind, you can truly transform your admin workload.

Automated data entry, intelligent candidate matching, and smart follow-up reminders free recruiters to focus on high-value relationship-building rather than repetitive busywork. For agencies, this means happier teams, faster placements, and the ability to scale without adding unnecessary overhead.

Improve your executive search reports and insights for smarter decision-making

Having access to clear, actionable data is crucial for agency recruiters, especially when working on high-stakes executive search projects. Legacy ATS solutions often require manual effort to piece together reports or rely on basic dashboards that lack depth.

With modern platforms like Atlas, you gain instant access to one-click executive search reports powered by AI. This means you can quickly track placement metrics, candidate engagement, pipeline health, and overall team performance, all without extra admin work. Smarter insights help agency leaders make faster, data-driven decisions and prove ROI to clients more effectively, ultimately strengthening your agency’s competitive edge.

Benefit from improved support and future-ready integrations

Migrating from a legacy ATS isn’t just about better features. It’s also about getting the support you need to grow confidently. Atlas offers dedicated, hands-on support that helps agencies through every step of their migration and beyond, ensuring recruiters never feel left on their own.

Plus, it’s constantly expanding its ATS integrations, including popular tools like WhatsApp and its powerful Chrome extension, so recruiters can work seamlessly across channels. This future-ready approach means your agency stays adaptable and connected, with the freedom to evolve as new tools and workflows emerge in the recruitment landscape.

What are the methods for migrating data from Bullhorn?

When migrating from Bullhorn to a new ATS like Atlas, it’s crucial to understand the available methods to ensure a smooth and secure transition. Here are the primary approaches:

CSV export data

For smaller datasets, Bullhorn allows exporting records directly to CSV files. This method is suitable for exporting specific lists, such as candidates or contacts.

However, it’s important to note that CSV exports may not include all associated records, like attachments or activity logs. Additionally, export permissions are typically restricted to admin users, and there might be limitations on the number of records you can export at once.

API access

For larger or more complex data migrations, utilising Bullhorn’s REST API is advisable.

This method allows for programmatic access to a wide range of data entities, facilitating a more comprehensive export. However, API access is generally available to Corporate or Enterprise editions and requires technical expertise to implement effectively.

Data backup request

If you need a complete copy of your Bullhorn data, including files and attachments, you can request a full data backup through Bullhorn Support.

This method is particularly useful when migrating all your records to a new system. Keep in mind that only Account or Support Contacts can make such requests, and the process may take several days to complete.

Data replication

Bullhorn offers a Data Replication service that continuously syncs your records to an external MS-SQL Server database.

This setup allows for direct SQL access to your records, enabling advanced reporting and integration capabilities. However, it requires specific hardware and software configurations and is typically used for business intelligence purposes rather than direct data migration.

Key takeaway: Choosing the right method for migrating from Bullhorn depends on the size and complexity of your data, as well as your technical resources. For a seamless transition to a modern ATS like Atlas, it’s essential to plan carefully and select the approach that best fits your agency’s needs.
