Migration guides

Moving high-volume workloads off OpenAI, Anthropic, or Gemini to self-hosted open-weight models (Llama, Mistral, DeepSeek) behind a gateway.

Re-platforming off Veeam, Commvault, or NetBackup: re-protecting workloads, parallel runs, and proving restores before you switch.

Moving off GitLab, Azure DevOps, or Bamboo to Gitea/Forgejo, Drone, Woodpecker, or Argo: repo mirroring and pipeline translation.

On-prem → cloud (adoption) and cloud → on-prem (repatriation): when each makes sense, native tooling, and the steady-state cost reality.

Moving workloads between AWS, Azure, GCP, and OCI: native migration services, IaC re-platforming, egress, and DNS cutover.

Leaving OpenShift, Tanzu, or Docker EE for upstream Kubernetes, Rancher/RKE2, or K3s: Velero-based moves and OpenShift-ism conversion.

Swapping CrowdStrike, SentinelOne, or Symantec for Wazuh, CrowdSec, or osquery: ringed agent rollout, detections, and dual-run.

Moving off Snowflake, Teradata, or BigQuery to ClickHouse, Trino, or DuckDB: open formats, SQL conversion, and reconciliation.

Moving off Oracle, SQL Server, or other commercial databases: licensing economics, schema/SQL conversion, and low-downtime cutover.

Replacing Palo Alto, Fortinet, Check Point, Cisco, or SonicWall with OPNsense or pfSense: rulebase export, VPN/IPS, and per-site cutover.

After HashiCorp's BSL change: moving Terraform→OpenTofu and Vault→OpenBao with compatible state/secret backends and no-op plans.

Replacing Okta, Entra ID, or Ping with Keycloak, Authentik, or Zitadel: directory sync, app re-federation, MFA, and per-app cutover.

Replacing F5, Citrix NetScaler, Kemp, or A10 with HAProxy, NGINX, or Traefik: translating rules, TLS, and swinging traffic safely.

Moving off Confluent, IBM MQ, or TIBCO to Apache Kafka, RabbitMQ, NATS, or Pulsar: bridging, repointing clients, and draining safely.

Replacing Datadog, Splunk, New Relic, or SolarWinds with open stacks (Prometheus/Grafana/Loki), what maps, what doesn't, and how to dual-run.

Moving off RHEL, Windows Server, or SUSE to Rocky, AlmaLinux, Ubuntu, or Debian: in-place conversion vs reprovision, and validation.

How to think about leaving Apigee, MuleSoft, or Kong Enterprise for an open gateway, what maps cleanly, and the one distinction that decides how hard the migration is.

Moving off Dell, NetApp, or Pure to software-defined/open storage (TrueNAS, Ceph, MinIO): data migration, performance, and cutover.

Moving off Cisco, Juniper, or Arista to open network OSes (SONiC, VyOS, FRRouting): HCL validation, config conversion, and pod-by-pod cutover.

How to think about replacing per-user VDI licensing with open remote-access and workspace-streaming tools, and where those tools genuinely fit versus where they don't.

Leaving VMware (or any hypervisor): how to choose a target, map vSphere concepts, and migrate VMs without surprises.
