High-Availability Server Migration.
A precisely sequenced infrastructure migration from AWS to Oracle Cloud using a blue-green cutover protocol — migrating all Docker volumes, n8n workflows, and persistent data with zero service interruption across a live production environment.
Recorded across the full production migration window.
The Problem
The client was running a suite of production automation workflows on AWS EC2. Rising compute costs and performance constraints on the instance tier required migration to Oracle Cloud Free Tier — a significant infrastructure shift. The challenge: the n8n workflows were business-critical, running 24/7. Any downtime would trigger missed pipeline triggers, broken webhook endpoints, and data loss.
The Build
Cuneihive designed a blue-green migration protocol: a parallel Oracle Cloud environment was provisioned and fully configured (Docker Compose, volume mounts, network config, SSL) while AWS remained live. Data volumes were replicated incrementally using rsync over a secure tunnel. DNS TTLs were pre-reduced 48 hours before cutover. The cutover itself was executed as a single coordinated switch: the Oracle environment was brought live, the DNS record updated, and AWS traffic drained over 60 seconds. The entire production switch took under 3 minutes with zero workflow failures recorded in post-migration log audit.

STATUS
DEPLOYED“We had no idea how to migrate without killing our workflows. Cuneihive designed the whole protocol, executed it overnight, and when I woke up everything was running on Oracle exactly as before. Not a single workflow failed.”
