Olla Systems' 4-stage cloud migration methodology moves your on-premises or overseas cloud workloads to OllaCloud's Nigerian private cloud - with full workload testing, rollback capability at every stage, and a dedicated solutions engineer from assessment to go-live.
Whether you're running on-premises legacy systems, overseas public cloud, or a mix of both. OllaCloud's migration team has a proven path for each.
Moving from legacy physical servers or VMware-based on-premises infrastructure to OllaCloud's OCI-compatible private cloud. Eliminate hardware refresh cycles and VMware licensing costs while gaining full cloud-native capabilities.
Moving from AWS, Azure, or Google Cloud to OllaCloud driven by NDPA compliance requirements, CBN data residency obligations, or the need to eliminate dollar-denominated billing and forex exposure.
Consolidating a fragmented mix of on-premises, overseas cloud, and local hosting into a single OllaCloud private cloud environment governed from one console, billed in one currency.
Our migration methodology is designed to eliminate the two things that make cloud migrations fail: insufficient assessment upfront and insufficient testing during cutover.
We start by understanding exactly what you're running and what regulations apply to it. Our solutions team analyses your existing workloads compute, storage, databases, networking and classifies each by data sensitivity, compliance requirement, and migration complexity.
A secure VPN is established between your existing environment and OllaCloud's Nigerian private cloud infrastructure. VCN configuration, security policies, and user access controls are set up on your dedicated OllaCloud environment before a single workload is moved.
Workloads move in phases, non-critical systems first, then core workloads. Each phase includes a full test period on OllaCloud before the original environment is decommissioned. Rollback is available at every stage there are no points of no return until you are satisfied.
After migration your team is trained on OCI tools, the console, and operational runbooks. Olla Systems transitions to ongoing managed cloud services 24/7 monitoring, patching, backup verification, and regulatory documentation support. You are never left on your own post-migration.
For years, Nigerian organisations deferred cloud migration because it felt risky and expensive. That calculus has reversed. Staying on legacy on-premises infrastructure now means rising hardware maintenance costs, VMware licensing increases, and growing regulatory exposure under NDPA and CBN frameworks.
Staying on overseas cloud means continued forex exposure on dollar invoices, growing NDPA cross-border transfer risk, and the latency penalty of serving Nigerian users from European data centres. Neither path is getting cheaper or safer.
Timeline depends on the scale and complexity of your workloads. A straightforward migration of development and staging environments can complete in 2–4 weeks. A full enterprise migration including core banking systems typically runs 8–16 weeks across all four stages, with each stage fully tested before the next begins.
For non-critical workloads, brief planned maintenance windows are scheduled. For critical systems: core banking, payment processing, live customer-facing applications — we use live migration and DNS cutover techniques that achieve near-zero downtime. Rollback is always available until you confirm the new environment is performing as expected.
In most cases, no. OllaCloud is OCI-compatible, which means existing Oracle workloads, standard VMs, containerised applications, and databases migrate without re-architecture. Applications currently running on AWS or Azure may need endpoint configuration changes, but the application code itself typically does not need to change.
Olla Systems transitions to ongoing managed cloud services 24/7 monitoring, Oracle patching, backup verification, capacity planning, and regulatory documentation support for NDPA and CBN examinations. Your team operates the platform using OCI tools they are trained on; we handle the infrastructure operations layer.
