Ericsson OSS and ENM migration and operations
We modernize legacy OSS-RC footprints, stabilize Ericsson Network Manager deployments and automate RAN/Core provisioning workflows. Our upgrade and migration plans cover release compatibility, rehearsed maintenance windows and who can authorize recovery.

Baseline the estate
Installed OSS-RC or ENM release, deployment model, node inventory and interface owners.
Confirm the change path
Vendor-supported transition path, representative interface tests, stop conditions and who can authorize recovery.
Execute in the approved window
Phased node waves inside the agreed maintenance window, with pre- and post-change checks and the agreed stop or recovery decision.
Validate and hand over
Alarm, configuration and performance flows tested on representative nodes with their owners; operator acceptance recorded.
Illustrative order of work for an OSS-RC or ENM change. Arrows show the sequence of our work, not network connections. Your installed release, deployment model and agreed interfaces set the actual plan.
Legacy OSS-RC Solaris/x86 estates and cloud-native ENM transitions become difficult to operate when northbound integrations are undocumented, CLI/AMOS scripts have no recovery checks, and alarm or performance data remains trapped in proprietary schemas. A successful cutover must preserve the node state, management interfaces and downstream data flows your operations teams depend on.
Audit LTE, 5G NR, IMS and Core element integrations against the installed and target release support matrices. Map topology and northbound consumers, group node re-homing into phased waves, and rehearse cutover with tested fallback scripts and application-owner acceptance.
Replace manual provisioning steps with version-controlled Python/Ansible workflows, supported ENM REST NBI calls and cmedit batch orchestration. Validate AMOS/Moshell procedures against the relevant element release, with authorization, idempotency checks and pre-/post-change evidence.
Build FM/PM/CM adapters using the interfaces your licensed estate exposes: SNMPv3, supported 3GPP bulk XML/JSON feeds, SFTP/TLS and REST. Normalize schemas and timestamps, handle retries and duplicate events, and feed Kafka, VES collectors, SIEM or data-lake consumers where compatible.
Size and validate compute, storage I/O, availability zones and networking for the vendor-supported virtualized or containerized deployment model. Test backup/restore, management-plane failover and capacity under representative node and telemetry loads.
We confirm interface availability, vendor entitlements, target-release support and node-owner responsibilities during scoping. Maintenance windows and recovery objectives are validated for your estate; uninterrupted service is not assumed.
Separate management, workload migration and hybrid routing paths, joined by validated platform dependencies.

Southbound element mediation is validated per installed ENM and node software release. MTV warm migrations replicate active blocks in the background and execute final cutover inside a scheduled window with verified ESXi fallback.

Wave-by-wave node lists, prerequisite checks, execution steps, stop conditions and per-wave rollback commands with named recovery owners.
Version-controlled scripts recording cell/node state, alarm deltas and KPI baselines before and after the maintenance window.
Production mediation adapters, schema mappings, retry behavior, API contracts and operating instructions committed to your repository.
Sizing and storage I/O findings, geo-redundancy checks where applicable, backup/restore results and measured failover evidence.
Element management, mediation and hybrid routing diagrams kept as Mermaid source in your repository and updated as waves complete.
Redacted change receipts, pre/post-check results and access records for each wave, ready for your auditors and regulators.
What the $14,500 sprint covers for this service. Access stays read-only throughout, and you keep the output whether or not you continue.
Days 1–3
Read-only review of OSS-RC and ENM node inventory, supervision and CM sync state, and the northbound REST NBI, SNMPv3 and Kafka/VES consumers.
Days 4–6
The nodes, scripts and northbound consumers that break on re-homing or an ENM upgrade, and the cmedit and AMOS checks each wave needs.
Days 7–9
Target topology in Mermaid (.mmd) source, a re-homing wave order with fallback triggers, and the design of the pre/post-check suite.
Day 10
Runbook drafts, the risk register and a fixed-scope backlog for your team or the paired principal pod.
We migrate and support telecom management systems and hybrid infrastructure, automate how workloads are validated and shipped, and build the portals and network API integrations that expose those platforms to your teams and customers.
A manager cutover that drops alarms or breaks provisioning is a network incident, not a project slip. The migration has to preserve every fault, configuration and performance flow its consumers rely on.
Best for
A successful manager cutover must preserve alarm delivery, configuration operations and performance-data collection. We trace those flows to their consumers and test them on representative nodes before expanding the change.
Bring to the review
Installed ENM or OSS-RC release, deployment model, node mix and interface inventory.
Build a release and node inventory, map northbound and southbound interfaces, and confirm the vendor-supported transition path. Then rehearse the cutover, validate the agreed FM/CM/PM flows and record stop conditions and who can authorize recovery.
Source and target releases with the vendor compatibility matrix, a node inventory with owners, PKI/CMPv2 and licence status, the northbound consumers of FM, CM and PM feeds, and an agreed maintenance window with a named decision maker.
Investigate missing alarms, failed configuration operations and interrupted performance collection using the affected nodes, timestamps and recent changes. Network-element and downstream-system owners participate in interface validation.
Release and node compatibility register, interface test results, cutover and recovery runbook, and operator acceptance record.
Confirm network-change authority, access owners and applicable vendor licenses and support entitlements. Include element owners when defining interface checks and recovery responsibilities.

Legacy OSS-RC and Ericsson ENM are distinct systems. We provide legacy OSS-to-Ericsson ENM migrations; your installed release, deployment model and the applicable vendor-supported path determine the migration scope.
You approve the network change and maintenance window. Before production work, we agree the test evidence, stop conditions, recovery prerequisites and the person authorized to make the recovery decision.
Confirm the owners of node access, vendor licenses and support entitlements during scoping. Our integration and support services do not replace vendor licensing or establish vendor authorization.
