IBM Cloud Classic has served as a stable and capable environment for thousands of workloads over the years. As IBM moves forward with a modern, flexible cloud architecture in IBM Cloud VPC, organizations now have the opportunity to evolve their infrastructure and take full advantage of next-generation capabilities.
The journey from Classic to VPC can present challenges - especially for complex, legacy, or highly customized environments. That’s where RackWare comes in.
As a long-standing IBM partner, RackWare is committed to helping IBM customers accelerate secure, low-risk modernization journeys. Whether the workload is running in IBM Cloud Classic or IC4V, our intelligent automation platform simplifies the transition to IBM Cloud VPC without disruption, rework, or compromise.
6 Common Migration Considerations and How RackWare Supports IBM Cloud Customers
1. Hypervisor Differences (No VMDK Conversion Needed)
Classic and VPC environments operate on different hypervisor technologies. In many cases, attempts to convert VMDKs introduce unnecessary risk or fail to deliver consistent results.
RackWare takes a smarter approach. We provision fresh, VPC-native VMs and overlay the original system image using intelligent file-level replication. This avoids conversion altogether, ensuring fast and reliable transitions across diverse OS and application stacks.
We also handle any device driver differences automatically, so workloads boot smoothly in the VPC target environment.
2. Storage Format Compatibility
Classic and VPC use different storage architectures, which can present compatibility challenges during direct migration.
RackWare resolves this by replicating data using our patented filesystem-level technology. We automatically provision storage in the VPC target environment and ensure data integrity throughout the process.
3. Legacy Operating Systems
Some Classic workloads run on older OS versions not natively available in VPC.
With RackWare, that’s not a blocker. Our solution provisions a compatible base image and applies the legacy workload over it, preserving configurations, applications, and user data. This allows IBM customers to modernize on their own terms, while maintaining continuity.
4. Networking Adjustments
Classic and VPC networking models differ. Stretching subnets between them can lead to operational challenges.
RackWare simplifies this by offering full isolation during migration and test cycles. Customers can retain their original IPs if needed, or update them - and RackWare takes care of all associated network reconfiguration, including DNS, interfaces, and gateways.
5. Boot Architecture (BIOS to UEFI)
IBM Cloud VPC uses UEFI, while Classic often runs BIOS-based workloads. That gap can cause boot failures with conventional tools.
RackWare bridges this automatically. Our boot translation handles BIOS-to-UEFI transitions behind the scenes, ensuring workloads launch correctly and reliably in VPC.
6. Physical Server Migration Support
For customers with physical servers in their Classic environments, RackWare offers robust support for physical-to-virtual and physical-to-physical migrations.
This extends IBM’s VPC benefits to workloads previously considered too difficult or expensive to move.
Helping IBM Drive Customer Modernization
RackWare fully supports IBM’s strategy to guide customers toward more agile, scalable, and modern cloud infrastructure. By removing technical obstacles and streamlining complex migrations, we help IBM accelerate cloud adoption, unlock new workloads for VPC, and enable seamless transitions from legacy environments.
With RackWare, IBM customers can:
Reduce migration timelines by 65%
Move workloads securely and efficiently
Support complex and legacy systems with confidence
Add a layer of protection with disaster recovery
