The state of cloud adoption is growing, and Gartner predicts that by 2026, 75% of organizations will have a transformation model predicated on cloud as the fundamental underlying platform. Cloud deployments can include public, private and hosted private solutions, but for those who have already begun their cloud migration, the majority of the implementations are hybrid or multicloud users.
This trend toward the adoption of cloud-native software and platform as a service (PaaS) is expected to increase as organizations continue to evaluate different cloud solutions. Indeed, 74% of U.S. infrastructure decision-makers say their firms are adopting containers with a PaaS in an on-premises or public cloud environment.
With more opportunities than ever to migrate critical enterprise data to the cloud, it’s important to have a full understanding of what it entails.
Cloud migration is the transfer of data, processes and applications from one existing datacenter to a cloud-based datacenter. This transfer could originate from a different cloud or an on-premises solution, but its destination is always a cloud environment.
Cloud migration usually involves moving to a cloud-computing infrastructure environment in one of these three categories:

As businesses embrace the cloud to harness its scalability, flexibility and cost efficiencies, they are faced with the challenge of choosing the most effective migration strategy.
For organizations to make informed decisions, they must understand the eight different types of cloud migration:
Rehosting is usually the fastest way to migrate to the cloud as it involves minimal changes to applications. Organizations replicate their existing infrastructure in the cloud by converting physical servers to virtual machines from on-premises datacenters to cloud environments.
While rehosting offers quicker migration and less disruption to operations, it does not fully exploit the benefits of cloud-native services or optimize costs.
Refactoring involves modifying applications to take advantage of cloud-native features and services. This includes breaking down single-piece applications into microservices, adopting serverless computing or using managed databases and storage solutions.
While refactoring requires more time, resources and expertise than rehosting, it leads to significant improvements in scalability, performance and cost efficiency in the long term.
Replatforming strikes a balance between rehosting and refactoring by making targeted optimizations to applications before migrating them to the cloud. Organizations may update certain components to better align with the target cloud platform's capabilities without redesigning the entire application.
This aims to achieve some benefits of cloud-native architecture while reducing the effort and risk compared of full refactoring.
Repurchasing is the replacing of existing on-premises software with cloud-based alternatives, typically in the form of SaaS. Instead of migrating existing applications, organizations adopt new cloud-native software that offers similar functionality.
This simplifies management, reduces infrastructure overhead and provides access to the latest features. However, it requires adjusting business processes and data migration.
Retiring involves identifying and decommissioning applications or services that are no longer necessary or relevant to the organization. Instead of migrating these redundant systems to the cloud, organizations choose to phase them out entirely.
Retiring legacy applications can streamline the migration process, reduce complexity and lower costs by eliminating unnecessary infrastructure and maintenance overhead.
Retaining keeps applications on-premises rather than migrating them to the cloud immediately. Organizations may choose to retain workloads due to regulatory requirements, data sensitivity or other considerations that make cloud migration impractical at the time.
They can revisit these decisions in the future as needed — as cloud technology evolves, business needs change or regulatory constraints ease.
Hybrid migration combines on-premises, private cloud and public cloud environments to meet the organization's requirements. This approach is useful when there is a need to retain workloads on-premises while migrating others to the cloud.
It allows organizations to leverage the benefits of both environments — the scalability, flexibility and security of the cloud — and the control over sensitive data or legacy systems of on-premises applications.
Application migration to the cloud is a more specific concept than just cloud migration. It moves a software application and all of its data and processes to a new cloud computing environment, usually from a legacy on-premises server.
The main benefit of this approach is that the ROI of cloud computing can quickly outstrip the hard and soft costs of operating on-premises.
From ROI to total-cost-of-ownership (TCO), migrating to the cloud and investing in future cloud computing infrastructure has proven to save organizations time and money, as well as to create a stronger IT team by allowing them to focus on what they do best (which may not be managing complex cloud infrastructure).
The benefits of cloud migration include:
Keeping on-premises hardware up-to-date is time-consuming and expensive, and adding or modifying solutions in it can take a long time and demand immense IT resources.
Organizations must be able to adapt new and existing business solutions quickly and easily across their enterprise. The best way to do that is to migrate to the cloud.
The highly fluid demands of business and a growing diversity of technologies can overwhelm teams of internal experts, leaving businesses under-supported. In addition, the current job market is challenging due to fewer on-premise experts and those who may have the experience can be hard to find, expensive and difficult to retain.
By migrating to the cloud and leveraging a leading cloud provider, IT teams can focus on their own expertise and support their business operations rather than expend precious time and knowledge learning and operating cloud infrastructure.
When migrating to a cloud powered by AWS, for example, organizations gain the robustness of AWS infrastructure as well as the specialized workforce it takes to properly capitalize on it.
Embracing a decentralized work environment has proven critical for keeping and hiring employees. Consider how migrating to a secure cloud solution helps maintain the tools for enterprise-wide connectivity by providing:
With more digitalization comes more data, and it needs somewhere to live and expand.
Leading cloud providers offer essentially exponential growth opportunities, from storage space to additional servers for supporting growth in application, web or processing. This means that worrying about the amount of space available for storage as your organization expands becomes a thing of the past.
In addition, responsive and standards-based cloud architecture gives users the flexibility to work effectively from various modern devices, enabling access to data and processes from anywhere, anytime.
Leading cloud providers meet stringent security demands across various industries. After migrating to the cloud, organizations can focus on executing their business plans while knowing the content is compliant, protected and encrypted, and resilient (always available).
Hosting solutions on-premises carries more than just risk: It carries huge capital expenses, startup costs and the ongoing operational cost of keeping infrastructure running.
Migrating to the cloud reduces or eliminates many of these costs, including hardware, networking equipment, staffing, overtime, database maintenance, physical and logical security, and even software upgrades.
Once the cloud is operational, the cost becomes purely an operational expense that can be budgeted for.
Migrating to the cloud opens opportunities to drive innovation. Cloud-enabled organizations can build new solutions faster, optimize business processes and adapt to changing markets quickly — all leading to a better ability to compete.
As organizations evaluate how and when to migrate to the cloud, it’s important to have a realistic understanding of current operations, capabilities and what’s on the horizon for future technology.
Use these considerations as a starting point for evaluating cloud migrations:
Migrating to the cloud is a daunting idea because datacenters and all they entail are precious assets to any organization.
Leading cloud providers and their partners should be able to provide a detailed roadmap for your cloud migration.
For example, when a Hyland customer — new or existing — is ready to migrate to the Hyland Cloud, our team has a process in place. Here’s a high-level cloud migration checklist for taking your content to the cloud:
Prior to launching an enterprise-transforming migration to the cloud, take the time to review all the content that will make the move. Cloud experts recommend:
Inventory your content
There are a variety of analytic approaches, automated tools and specialist firms to help with this evaluation process. Any redundant, obsolete or trivial (ROT) content should be disposed of in a legally defensible manner.
Assure content is in context
Cost and time considerations will determine whether you do this processing before or after content is migrated to the cloud.
Once you’ve identified which content will be moved to the cloud, send it to your cloud provider so they can begin setting it up in its new home on the cloud.
> Tip: Remember what you shared. You don’t want to send duplicate data during updates before go-live.
Once the cloud solution is ready for testing, access it and start testing. Track your changes and align with your cloud provider on any changes they make, then collaborate to assure those changes are applied during go-live.
Once all testing is complete and the solution is working as expected, get a go-live date on the calendar. Good cloud partners will try to accommodate the most convenient time for your organization when scheduling the go-live— including nights and weekends — to minimize day-to-day disruptions.
> Tip: Wait until testing is complete before setting the go-live date. This avoids schedule changes due to unforeseen delays.
Stop all on-premises solution work. A clean cutover from on-premises to cloud is best, so request users avoid transaction creation in the on-premises solution during the final migration.
> Tip: Upload a fresh database backup and any remaining disk group data. Its size is generally the largest time constraint in the go-live timeline.
All content is in place, the database is restored and all the changes noted during the initial testing phase are configured. Before go-live, this is a good time to give the environment one last round of testing to make sure everything is operating as expected.
Simple as that. Start enjoying the benefits of your migration to the cloud.
