Why Cloud-to-Cloud Migration Is on the Rise

Rebecca Feldman

With all the attention on AI and next-generation technologies, it’s easy to overlook just how far the cloud journey has progressed. More than a decade has passed since public cloud compute became mainstream, and enterprise adoption has evolved dramatically.

Today, we’re entering a new phase of that evolution. Organizations that already migrated to the cloud are reassessing where and how their workloads operate. Increasingly, that reassessment is leading to one conclusion: it’s time to move again, but this time from one cloud to another.

Cloud-to-cloud migration is no longer a niche initiative. It’s a strategic decision driven by cost, complexity, performance, and long-term business alignment.

Below, we explore how we got here, and why this next shift is accelerating.

Phase One: Speed Over Structure

In the early days, cloud adoption was driven by urgency and experimentation. The first workloads to migrate were typically:

Pilots and proof-of-concepts
R&D initiatives
Innovation teams needing rapid experimentation
Projects that couldn’t wait for infrastructure procurement cycles

The value proposition was simple and compelling: instant provisioning, elastic scalability, and rapid iteration.

Cloud was an accelerator.

Phase Two: The Strategic Exit from Data Centers

As cloud capabilities matured, so did enterprise thinking.

Leadership teams began asking more fundamental questions:

Is running global data centers core to our business?
Does managing infrastructure create competitive advantage?
Should we reduce or eliminate our data center footprint?

For many organizations, the answer was clear. Cloud became not just an innovation platform, but foundational infrastructure.

This led to large-scale migrations to Amazon Web Services (AWS), Microsoft Azure, Oracle Cloud Infrastructure (OCI), and Google Cloud. Hybrid infrastructure services and hybrid infrastructure management models became common, with enterprises shifting substantial environments into public cloud while maintaining certain on-premises systems.

Cloud adoption moved from experimental to strategic.

Phase Three: Tackling the “Last Mile”

Now, more than a decade in, organizations are confronting what they left behind.

Mission-critical systems often remained on-premises because:

They were too complex for simple lift-and-shift migrations.
They ran the core business.
The risk of disruption felt too high.

In healthcare, for example, most electronic medical records (EMRs) historically ran in production environments on-premises or in private clouds, often within managed private cloud or hybrid private cloud environments. Only in recent years have major vendors enabled full-scale production deployments in the public cloud.

The same story plays out across manufacturing, retail, and finance, where legacy ERP systems remain on-premises or were moved to the cloud without meaningful optimization.

Today, organizations with greater cloud maturity are returning to modernize these systems properly. They are re-evaluating hosting strategies, infrastructure design, and long-term platform roadmaps.

The “last mile” of cloud transformation is underway.

The Rise of Cloud-to-Cloud Migration

Here’s where the evolution becomes especially interesting.

Over the past decade, many enterprises adopted multi-cloud environments—sometimes strategically, sometimes organically. For example, core workloads may reside in AWS, analytics in Azure, and specific applications in OCI or GCP.

In theory, multi-cloud offers flexibility, redundancy, and best-of-breed services. In practice, it can introduce operational complexity, requiring more advanced hybrid operations support, co-managed infrastructure services, and 24×7 infrastructure monitoring to maintain performance and governance. It can also lead to higher management overhead, skill fragmentation across teams, and reduced purchasing leverage.

As a result, organizations are stepping back and asking a new question:

Does consolidation make more sense?

Increasingly, the answer is yes.

We are seeing more companies make intentional decisions to consolidate with a primary cloud provider over the next 12–to-24 months, which is driving a noticeable rise in cloud-to-cloud migrations.

Here’s why.

1. Economies of Scale

Consolidating spend with one provider can lead to:

Stronger enterprise agreements
Higher discount tiers
Simplified licensing structures
Greater financial predictability

2. Operational Simplicity

Managing identity, networking, security, governance, and monitoring across multiple clouds increases complexity exponentially.

Standardizing on one primary platform reduces duplication, improves visibility, and creates opportunities to streamline managed infrastructure services across the enterprise.

3. Skill Depth Over Skill Fragmentation

It’s significantly easier to build deep architectural and operational expertise within one ecosystem than to maintain broad proficiency across several. Consolidation enables stronger internal capabilities and more efficient teams.

4. Performance and Architecture Optimization

Modernizing legacy ERP systems, large databases, and mission-critical workloads often benefits from tighter integration within a single cloud environment. Consolidation can enhance performance, resilience, and scalability while simplifying architecture.

5. Increased Cloud Maturity

Perhaps most importantly, organizations are simply more prepared now.

They:

Understand cloud operations more deeply
Have mature governance and security frameworks
Possess tested migration playbooks
Have executed large-scale transformations before

This maturity provides confidence to migrate core systems without disrupting the business and to optimize rather than merely relocate workloads.

Not the End of Multi-Cloud, But a Recalibration

Multi-cloud strategies are not disappearing. There are valid reasons for distributing workloads, including:

Regulatory requirements
Resilience and redundancy goals
Access to specialized services
Geographic constraints

However, many organizations are shifting from multi-cloud to intentional architecture driven by long-term strategy.

For some, that intentional strategy means consolidation.

What This Means for Enterprises

Cloud-to-cloud migration represents the next natural phase of the cloud lifecycle:

First came experimentation.
Then widespread adoption.
Now comes refinement and optimization.

Organizations are no longer asking whether to use the cloud. They are asking how to use it better.

That is why cloud-to-cloud migration is rising.

Why the Right Partner Matters

Reassessing cloud strategy—whether modernizing legacy systems or consolidating providers—introduces complexity and risk. These decisions directly impact core business systems, customer experience, compliance posture, and long-term cost models.

Success requires more than technical execution. It requires expertise in managed infrastructure services, hybrid infrastructure management, and co-managed infrastructure services across complex, multi-cloud environments.

Navisite, Part of Accenture, brings subject matter experts across all major hyperscalers—AWS, Azure, GCP, and OCI—along with extensive experience supporting enterprise platforms such as Oracle E-Business Suite, JD Edwards, SAP, and large-scale database environments like Oracle Exadata. This combination of cloud and application expertise enables organizations to migrate even their most complex, business-critical systems with confidence.

As enterprises enter this next phase of cloud evolution, the goal is not simply to move workloads, but to move the business forward strategically.
