The email arrives like it always does. Quietly, months before the deadline. Long enough to feel like a choice. Short enough that the pressure is already building. The Oracle renewal notice. And with it, the number.
For most enterprises, what follows isn’t a decision. It’s a negotiation with reality. The licensing costs have compounded again. The support fees are non-negotiable. And somewhere in the room, someone mentions the migration project, the one that started two years ago, consumed months of DBA time, stalled on compatibility issues nobody anticipated, and quietly got parked when the business couldn’t absorb another delay.
The decision gets deferred. The renewal gets signed. And the gap widens. The business still isn't AI-ready. Still isn't sovereign. Still tied to a vendor that has been using migration complexity as a retention strategy.
This is the story we’ve heard from enterprises for years. And it’s exactly the story EDB Agentic Migrations was built to end.
The numbers are stark. 75% of enterprise data is still locked in legacy systems. 94% of enterprise database migrations run late or over budget. These aren’t edge cases, they’re the norm.
The reason is almost always the same: migrations stall at the last mile. The assessment looks manageable. The plan looks solid. And then the PL/SQL incompatibilities surface, the code rewrites pile up, the DBAs get buried in compatibility triage, and a project that was supposed to take six months becomes eighteen. Every month of delay means more unnecessary licensing costs, more cloud egress fees, more DBA capacity consumed by migration work instead of the AI initiatives the business is waiting on.
And for enterprises in regulated industries, financial services, healthcare, government, the problem runs even deeper. Moving to cloud managed Postgres just trades one form of lock-in for another: unpredictable pricing, consumption-based costs, and a hard dependency on cloud-only features that makes leaving even harder. Some organizations won’t even have that option much longer, as sovereignty mandates increasingly make hyperscaler deployments a compliance risk rather than a convenience.
The migration problem isn’t a skills problem. It’s a scale and complexity problem. And it’s one that human teams alone were never going to solve.
EDB Agentic Migrations is an AI-driven workflow that orchestrates the end-to-end move from legacy Oracle and cloud-locked Postgres databases into a sovereign, enterprise-hardened EDB Postgres AI platform, automatically, securely, and in days rather than months.
Agentic Migrations is built on three core principles:
1. One interface to assess and migrate
From first assessment to final cutover, everything happens inside a single interface with no third-party portals and no data leaving the customer's environment. Customers can assess databases at scale, from a handful to hundreds of source databases at once, and get a complete, accurate picture of their modernization project before committing to a single step. New this quarter, that assessment now extends to the application layer too, with SQL statement compatibility checking against EDB Postgres.
2. Agent-driven workflow
Where traditional migration tools stall, Agentic Migrations handles the manual, complex work: spinning up the new destination cluster, resolving PL/SQL incompatibilities, moving data and schema, all without requiring DBA intervention at every step. The process that used to consume 50 or more manual steps now runs through a single automated workflow. A migration that used to take twelve to twenty-four months now takes days.
3. Sovereign by design
Every migration step runs inside the customer's own environment. No data touches an external system. No third-party tool sees the schema. The entire process, including AI-assisted remediation, stays within the customer's security perimeter. For air-gapped environments and regulated industries, that's not a nice-to-have. It's the difference between a migration that can happen and one that legally cannot.
The migration problem isn't a skills problem. It's a scale and complexity problem. Enterprise migrations involve hundreds of interdependent steps, dozens of stakeholders, and compatibility challenges that surface unpredictably across months of execution. No human team, however skilled, can run that process at the speed and consistency the business needs. That's not a criticism of the people involved. It's an acknowledgement that the problem has outgrown the tools available to solve it manually.
This is where agents change the equation. Not by replacing the expertise your team brings, but by augmenting it in a way that dramatically increases what that expertise can deliver. The DBA who once spent months triaging PL/SQL incompatibilities one by one can now oversee an agent that handles that triage automatically, at scale, and without dropping a single edge case. The migration architect who defined the process now defines the guardrails, and the agent executes within them. Humans move up the stack. Throughput goes up with them.
Agentic Migrations isn't built on generic AI. It's built on more than 20 years of EDB engineers solving Oracle migration problems at enterprise scale, the compatibility edge cases, the PL/SQL constructs that break tools built by teams who've never lived inside an Oracle environment, the performance tuning decisions that only come from having seen thousands of production migrations go right and wrong.
That expertise is what's embedded in the agent. When the migration co-pilot resolves a PL/SQL incompatibility, it's drawing on the same knowledge base that EDB's engineers have built over two decades of Oracle to Postgres work. When it makes an automated decision about schema conversion, it's applying the same judgment a senior EDB migration architect would, at machine speed, at any scale, inside your environment.
What the Numbers Actually Mean
Up to 80% TCO savings compared to Oracle. 95% fewer code rewrites. Migration timelines cut by half. These numbers land differently when you put them in context.

The USDA Forest Service needed to escape Oracle on a tight government timeline and budget. EDB delivered the migration ahead of schedule, at less than 30% of the original cost, with 70% better performance. EDB customers using Agentic Migrations are already reporting up to 40% reduction in effort on complex migration workflows, and the USDA result is exactly the kind of outcome that number points to, not by asking teams to work harder, but by removing the frustrating, repetitive, high-stakes work that was slowing them down in the first place.
For Application Developers and teams, the shift is from being buried in compatibility rewrites to being the person who reviews the agent's work. Agentic Migrations doesn't replace your team's expertise, it removes the work your team shouldn't be doing. The migration AI co-pilot handles incompatibility resolution. The bulk registration capability, which lets teams assess dozens of databases simultaneously, means a full estate can be profiled and ready in the time it used to take to do one. And when the migration completes, the team doesn't just land on a newer database, they land on an AI-ready, sovereign Postgres platform where new initiatives can start immediately, without waiting for another modernisation project to catch up.
For Platform Architects and Security teams, the biggest shift is moving from passive observers to active participants. Rather than being handed a migration plan to review after the fact, the guardrails are defined by your team upfront. What the agent is authorised to do, when, and under what conditions. The migration executes within those boundaries, and nothing happens outside them. Security teams go from being the last line of defence to being the architects of the process itself.
For VP Infrastructure and Economic Buyers, the message is straightforward: the migration you've been deferring because the last one stalled is now a different proposition. EDB gives you a credible, auditable path to 80% TCO savings with a timeline measured in days. The Oracle renewal that felt like a trap now has an exit.
