How to Choose an Oracle Cloud Migration Partner: What Sets Cornerstone Data Systems Apart

Moving to Oracle Cloud Infrastructure (OCI) sounds simple. Lower costs, better performance, less hardware to manage. But the real outcome depends on one thing most companies overlook: who runs the migration. The same OCI platform can go smoothly in one team’s hands and stall out in another’s. The technology isn’t usually the problem. The Oracle Cloud migration partner is.

If you’re evaluating OCI migration services right now, this guide is here to help. Use it to ask sharper questions before you sign. Not after something goes wrong.

Why “Just Move It to OCI” Isn’t a Strategy

Most vendors can spin up compute in OCI. Far fewer can safely move a live Oracle database. Oracle databases come with strict licensing rules. They run custom code. Other apps connect to them. They need to stay up. Treat that move like a generic cloud swap, and something usually breaks. Budgets run over. Timelines slip. This is one of the most common ways OCI projects go wrong.

The good news: most of this risk is avoidable. It just takes the right partner asking the right questions before work starts, not after.

Want the bigger picture on why companies move to OCI in the first place? Read our OCI migration primer here. This guide skips that part. It focuses on one question: who should run your migration?

Four Questions to Ask Before You Choose an OCI Migration Partner

These four questions cut through the sales pitch fast. Ask them early, before you sign anything.

1. Have they migrated databases at your scale?

Tools like RMAN, Data Pump, and GoldenGate handle most Oracle-to-OCI moves well. But at large scale, standard tools often fall short. Think huge databases. Think strict uptime windows. Cornerstone’s team builds custom data-transfer pipelines for exactly these cases. One recent project moved a 60-terabyte Oracle database for a regional health system. A standard export-and-import approach would have kept the system down far too long. So the team built something better instead.

Ask any migration partner this directly: what’s the largest, most complex Oracle migration you’ve actually run? What did you build when the standard tools fell short?

2. Do they understand Oracle licensing, not just cloud infrastructure?

Any cloud generalist can spin up OCI compute and storage. Far fewer understand Oracle licensing well enough to save you money on it. Licensing rules shift across VM, Bare Metal, Exadata, and Autonomous Database options. Get this wrong, and your promised savings quietly disappear. You end up paying more, not less.

3. What happens after go-live?

Migration day gets all the attention. But what matters more is who manages your database the Monday after. Cornerstone’s Database Administration Services team provides ongoing Oracle DBA support after go-live. That means proactive monitoring, tuning, and 24/7 coverage. Your migration shouldn’t be a one-time event followed by silence. Before you sign with any partner, ask exactly what happens after launch — and who you’ll call at 2 a.m. if something breaks.

4. Can they support regulated, mission-critical environments?

Banks, hospitals, and government agencies can’t treat a cloud move as a purely technical job. It’s a compliance job too. Cornerstone works within SOC 2, HIPAA, GDPR, and PCI-DSS rules as a matter of course, not as a special add-on. If your setup has to meet compliance rules, ask your migration partner one thing: have they actually worked inside those rules before? Not just read about them?

What Sets Cornerstone Data Systems Apart on OCI Migrations

Cornerstone is a certified Oracle partner. The team’s expertise spans Oracle databases, licensing, Exadata, and OCI itself. But the migrations that matter most to enterprise IT leaders are rarely the simple ones. Here’s what sets Cornerstone apart on the hard ones:

• Custom engineering when standard tools hit their limits. RMAN, Data Pump, and GoldenGate cover most jobs. When they don’t — at multi-terabyte scale, with tight uptime windows — Cornerstone builds a custom pipeline instead of forcing the job to fit the wrong tool.
• A track record with large, complex environments. The 60TB healthcare migration below is one of several large-scale Oracle projects the team has run. Each one required careful sequencing so business-critical systems kept running.
• Support that doesn’t end at go-live. Around-the-clock Oracle DBA support continues after the migration. The team is U.S.-based, headquartered in Atlanta, with clients nationwide.
• A certified Minority Business Entity (NMSDC-certified MBE). That can help meet supplier diversity goals alongside deep OCI expertise.

A Real-World Example: A 60TB Healthcare Database Migration

One recent project involved a 60-terabyte Oracle database for a health system. The rules were strict: stay up, and never lose a single record. A standard export-and-import window just wasn’t realistic at that size. So Cornerstone’s team built a custom data-transfer pipeline instead. The move ran in coordinated phases. The team checked data integrity at every step. Clinical and front-desk staff never lost access to the systems they use every day. This kind of project can’t be solved with a generic checklist. It has to be engineered from scratch.

Frequently Asked Questions

How long does an OCI migration take for a large Oracle environment?
It depends on database size, uptime needs, and how many apps connect to it. A thorough check-up front makes the actual move far more predictable. Skipping that step is the most common cause of delays. Most large moves take a few weeks to a few months, start to finish.

Can Cornerstone migrate Oracle E-Business Suite or JD Edwards to OCI?
Yes. Cornerstone migrates Oracle databases and the applications that depend on them, including E-Business Suite and JD Edwards environments.

Do you provide DBA support after the migration is complete?
Yes. Cornerstone’s Database Administration Services team gives you ongoing, around-the-clock Oracle DBA support after go-live. The relationship doesn’t end at launch. It’s just getting started.

Is Cornerstone an Oracle-certified partner?
Yes. Cornerstone Data Systems is a certified Oracle partner, with expertise across Oracle databases, licensing, Exadata, and Oracle Cloud Infrastructure.

Choosing the Right Partner Matters More Than Choosing the Platform

OCI itself is a strong platform. What determines whether your migration goes smoothly is the Oracle Cloud migration partner running it. Their experience at your scale. Their grasp of Oracle licensing. Their commitment to what happens after go-live. Those three things matter more than any feature list.
