Migration Guide

Move your workloads with confidence

Follow these steps to migrate your applications from legacy platforms to Open Source Cloud.

1

Audit Your Current Stack

Document your databases, services, environment variables, and dependencies. List all add-ons and integrations.

2

Create OSC Account

Sign up for free at app.osaas.io. No credit card required to start.

3

Provision Services

Use our MCP integration with your AI agent to set up databases, caches, and storage. Or browse the catalog and deploy manually.

4

Deploy Your Application

Push your code as a hosted application. Configure environment variables and custom domains.

5

Test Thoroughly

Run your test suite against the new infrastructure. Verify all integrations work as expected.

6

Switch DNS

Update DNS records to point to your new deployment. Keep the old platform running until migration is verified.

Common Stack Migrations

Typical configurations and their OSC equivalents

Node.js + PostgreSQL

Legacy: Dyno + Postgres add-on
OSC: Hosted App + PostgreSQL service

Connect via standard connection strings

Rails + Redis

Legacy: Web dyno + Redis add-on
OSC: Hosted App + Redis/Valkey service

Standard Redis protocol, drop-in replacement

Python + S3

Legacy: Worker dyno + S3 add-on
OSC: Hosted App + MinIO (S3-compatible)

Use same S3 SDK, just change endpoint

Pricing Comparison

Typical workload costs

Compare pricing for a typical production workload: 1 web app, 1 PostgreSQL database, 1 Redis cache, and regular traffic.

Legacy Platform: ~$50-100/month (limited free tier)

OSC Personal Plan: €15/month (plus generous free tier)

Save up to 70% on infrastructure costs

Exact costs depend on usage patterns. OSC charges only for active services with transparent, predictable pricing.
