In January 2024, a manufacturing client in Laguna sent us an email that many IT directors across Southeast Asia were sending around the same time: "Our VMware renewal just came in. It is 12x what we paid last year. We need alternatives. Now."
That email kicked off what became the busiest year of our careers. Between February 2024 and December 2025, we completed 31 migrations from VMware vSphere to Sangfor HCI across the Philippines. Manufacturing, retail, healthcare, BPO, education — we touched every industry. And we learned a lot about what works, what does not, and what nobody tells you about HCI migration.
This is the honest playbook. No vendor marketing. No sugarcoating. Just what we learned from moving 30+ enterprises off VMware to Sangfor.
What Is Sangfor HCI?
Sangfor HCI (Hyper-Converged Infrastructure) is a unified platform that combines compute, storage, and networking into a single appliance. Think of it as the opposite of traditional infrastructure where you buy separate servers, SAN switches, and storage arrays.
The core product is Sangfor aServer, which packages x86 compute nodes with Sangfor proprietary distributed storage (called HCI Storage or NeuCloud). The hypervisor is Sangfor's own, based on KVM. Management is handled through a single web console called Sangfor IAM (Infrastructure Access Manager).
Sangfor has been shipping HCI since 2015. They are the leading HCI vendor in China and have significant market share in Southeast Asia. In the Philippines specifically, they have partnered with local distributors like Cebu Pacific Technologies and have deployed in manufacturing, retail, and government sectors.
Key differentiator vs VMware: no per-VM licensing. You buy the hardware appliance, and the hypervisor and storage are included. No subscription fees. No per-core charges. This is the main reason clients are migrating.
Why Migrate from VMware? The Math That Matters
Let us talk numbers, because that is what drives these decisions.
Before the Broadcom acquisition, a typical mid-sized Philippine enterprise (100-200 VMs) paid roughly 15,000-25,000 USD per year for VMware vSphere Enterprise Plus licensing. After Broadcom restructured VMware licensing in 2024, that same client saw quotes ranging from 80,000 to 300,000 USD per year — depending on how Broadcom calculated the "subscription" conversion.
One manufacturing client in Batangas received a renewal quote of 185,000 USD for 180 VMs. Their previous VMware cost was 18,000 USD. That is a 10x increase. Their total IT infrastructure budget was 400,000 USD. VMware alone would consume nearly half.
Compare that to Sangfor HCI. For the same 180 VMs, a Sangfor aServer deployment with 6 nodes costs approximately 120,000-150,000 USD as a one-time capital expenditure. No annual licensing fees. The hardware has a 5-year warranty. After year 3, the total cost of ownership is significantly lower than VMware — even at pre-Broadcom prices.
Here is the TCO comparison we show clients:
Year 1: VMware 185K USD (license) + 25K USD (support) = 210K USD. Sangfor: 135K USD (hardware) + 10K USD (support) = 145K USD. Savings: 65K USD.
Year 3: VMware: 210K USD x 3 = 630K USD. Sangfor: 145K USD + 30K USD (years 2-3 support) = 175K USD. Savings: 455K USD.
Year 5: VMware: 210K USD x 5 = 1,050K USD. Sangfor: 145K USD + 50K USD (years 2-5 support) = 195K USD. Savings: 855K USD.
These numbers are real. We have verified them against actual client contracts.
Our Migration Methodology: 7 Phases
After 31 migrations, we have a repeatable process. Here is how we do it.
Phase 1: Workload Assessment (Week 1-2)
We inventory every VM on the VMware environment. For each VM, we document: OS version, CPU/memory/disk allocation, actual utilization (30-day average), dependencies, and licensing restrictions.
The output is a three-tier classification:
Tier 1 (Critical): These VMs require near-zero downtime migration. Databases, ERP systems, production applications.
Tier 2 (Important): These can tolerate 2-4 hours of downtime during migration. File servers, internal tools, non-critical applications.
Tier 3 (Flexible): These can be rebuilt on Sangfor if migration is too complex. Test environments, dev servers, archived systems.
Typical finding: 60% of VMs are Tier 3, 25% Tier 2, 15% Tier 1. Most clients overestimate how many Tier 1 VMs they have.
Phase 2: Hardware Sizing and Procurement (Week 2-4)
Sangfor sizing is based on current utilization plus 30% headroom. Unlike VMware where you can over-provision memory (thanks to ballooning and compression), Sangfor HCI is more conservative. We size for actual usage, not theoretical maximums.
For a typical 180-VM deployment: 6 aServer nodes (each with 2x Intel Xeon, 256GB RAM, 4x 1.92TB NVMe SSDs), plus 10GbE network switches. Total hardware cost: approximately 120,000-135,000 USD.
Procurement lead time in the Philippines: typically 4-6 weeks. We order hardware in Phase 2 so it arrives by Phase 4.
Phase 3: Network Design (Week 3-4)
Sangfor HCI requires a flat network topology for optimal performance. Traditional VMware environments often have complex VLAN structures. We simplify during migration.
Minimum network requirements: 10GbE for storage traffic (mandatory), 1GbE minimum for management. We deploy dedicated storage VLANs and use jumbo frames (MTU 9000) for inter-node communication.
One lesson learned: do not use the same switch for storage and production traffic unless you implement QoS. We learned this the hard way when storage replication saturated the uplink during a production workload spike, causing both storage and application performance to degrade.
Phase 4: Pilot Migration (Week 5-6)
We always start with 3-5 Tier 3 VMs as a pilot. This validates the hardware, network, and our migration procedures without risking production systems.
For pilot VMs, we use Sangfor's built-in migration tool (Sangfor IAM Migration) which can do online VM conversion from VMware VMDK format to Sangfor's QCOW2 format. The tool handles most cases, but we have hit edge cases with legacy OS versions (Windows Server 2008, older Linux kernels) that required manual conversion.
Pilot success criteria: VM boots correctly, network connectivity confirmed, application functional, performance within 10% of VMware baseline.
Phase 5: Production Migration (Week 7-10)
This is the main event. We migrate Tier 2 VMs first (lower risk), then Tier 1 (highest risk but most value).
Migration approach for Tier 2:
1. Schedule maintenance window (typically Saturday night to Sunday morning).
2. Shut down VMware VM. Export final snapshot.
3. Convert and import to Sangfor. This takes 2-8 hours depending on VM disk size.
4. Configure network (VLAN, IP, DNS).
5. Power on and validate.
Migration approach for Tier 1 (zero-downtime):
1. Set up Sangfor target VM with mirrored configuration.
2. Use database-native replication (SQL Server Always On, MySQL replication) to keep data in sync.
3. During maintenance window, switch application connection strings to Sangfor VM.
4. Validate, monitor, rollback if needed.
Our fastest Tier 1 migration: a 500GB SQL Server database migrated with zero data loss and 12 minutes of application downtime. Our slowest: a legacy ERP system with hardcoded IP references took 6 hours because every configuration file needed manual updates.
Phase 6: Validation and Optimization (Week 11-12)
After all VMs are migrated, we run a two-week validation period. During this time, we monitor performance metrics daily and compare against VMware baselines.
Common findings during validation:
Storage IOPS on Sangfor is typically 20-40% higher than VMware vSAN for the same workload. The NVMe-based storage architecture is more efficient.
Memory utilization is tighter. We often need to adjust VM memory allocations downward because Sangfor does not have VMware's memory overcommitment features.
Network latency between VMs on the same Sangfor cluster is typically under 1ms, comparable to VMware vSphere distributed switches.
Phase 7: Decommission and Knowledge Transfer (Week 13)
Once validation is complete, we decommission the VMware infrastructure. This includes removing VMware licenses (which clients are usually happy about), migrating any remaining VMware-specific integrations (vRealize, NSX if used), and training the IT team on Sangfor management.
Knowledge transfer is critical. We run a full-day workshop covering: daily operations (monitoring, alerts), weekly tasks (backup verification), monthly tasks (capacity planning, firmware updates), and emergency procedures (node failure, storage rebuild).
Best Practices for VMware to Sangfor Migration
1. Start the conversation with your VMware account team early. In some cases, we have negotiated 40-50% discounts on VMware renewals as clients demonstrate Sangfor as a viable alternative. Even if you decide to migrate, the threat of leaving gives you negotiating power.
2. Do not migrate everything. Keep VMware for workloads that genuinely benefit from VMware-specific features (NSX micro-segmentation, vRealize Operations, Tanzu for Kubernetes). Migrate the 80% that runs on standard vSphere to Sangfor.
3. Budget for the transition. While Sangfor saves money long-term, Year 1 includes both VMware exit costs and Sangfor entry costs. Plan for a 10-15% higher infrastructure spend in Year 1.
4. Test your backup solution compatibility. Not all backup vendors support Sangfor. Veeam and Acronis do. Verify before you migrate.
5. Plan for the cultural shift. VMware administrators have 10+ years of muscle memory. Sangfor's management interface is different. Invest in training.
6. Keep a rollback plan. For every Tier 1 migration, we maintain a VMware snapshot that we can restore within 2 hours if the Sangfor migration fails.
7. Document everything. Every VM configuration, every IP address, every DNS record. Migration is the perfect time to audit your infrastructure documentation.
Common Mistakes in VMware to Sangfor Migration
Mistake 1: Skipping the pilot. We had one client who wanted to skip Phase 4 and go straight to production migration. We pushed back. During the pilot, we discovered their backup software was incompatible with Sangfor's storage format. That discovery saved us a production disaster.
Mistake 2: Ignoring licensing. Some Windows Server and application licenses are tied to specific hardware. Moving from VMware to Sangfor may require re-licensing. Check this before migration, not after.
Mistake 3: Underestimating storage performance requirements. Sangfor HCI uses all-flash storage, which is fast, but the IOPS characteristics differ from VMware vSAN. Profile your workloads before migration and size accordingly.
Mistake 4: Not training the IT team. The IT director who manages VMware daily needs to manage Sangfor daily. If they are not comfortable with the new interface, they will call support for every minor issue — costing you time and support credits.
Mistake 5: Migrating during peak business periods. We scheduled a migration for a retail client during December (their busiest month). Bad idea. The maintenance window kept getting shortened because the business could not afford downtime. Migrate during your quietest period.
Conclusion: The Math Is Simple, the Migration Is Not
The cost savings from VMware to Sangfor are undeniable. Over 5 years, our clients save between 400K and 900K USD depending on scale. But migration is not trivial — it requires planning, testing, and expertise.
If you are considering the move, here is our recommendation:
1. Get your VMware renewal quote first. Know your baseline.
2. Contact a Sangfor partner for a sizing assessment. Most offer free assessments.
3. Compare the 5-year TCO. Include hardware, licensing, support, and staff training costs.
4. Run a pilot with 3-5 non-critical VMs. See how it feels.
5. Make the decision with data, not fear.
We are not anti-VMware. VMware is excellent technology. But when the licensing math no longer works, you owe it to your organization to explore alternatives. Sangfor HCI is a proven alternative — and the 31 migrations behind us prove it works.

FAQ
Q: How long does a typical VMware to Sangfor migration take?
For a mid-sized environment (100-200 VMs), expect 10-14 weeks from assessment to decommission. The pilot takes 2 weeks, production migration takes 4-6 weeks, and validation takes 2 weeks. Large environments (500+ VMs) may take 4-6 months.
Q: Can we run VMware and Sangfor in parallel during migration?
Yes, and we recommend it. During the migration period, both environments coexist. VMs on VMware continue to operate normally while migrated VMs run on Sangfor. This gives you a clean rollback path if anything goes wrong.
Q: What happens to our VMware licenses after migration?
VMware perpetual licenses retain their value — you can sell them on the secondary market. Subscription licenses can typically be cancelled at the next renewal date. However, check your specific contract terms as Broadcom has changed some licensing terms.
Q: Does Sangfor support the same hypervisor features as VMware?
Sangfor supports the core features: live migration, high availability, fault tolerance, snapshots, and distributed switching. Advanced features like NSX micro-segmentation or vRealize Operations have no direct Sangfor equivalent. Evaluate whether you need those features before migrating.
Q: What about Kubernetes and container workloads?
Sangfor offers Sangfor KubeSphere, a Kubernetes management platform. It is not as mature as VMware Tanzu, but it covers the basics. If Kubernetes is a significant part of your infrastructure, factor this into your decision.
