What Is Calypso?

Calypso is a standalone Oracle database migration assessment tool. Connect it to any Oracle database, and it runs 281 read-only queries to deliver a comprehensive analysis of your environment — configuration, performance, storage, capacity, licensing, schema compatibility, and migration readiness — all in one assessment.

No agents to install. No data modified. No downtime. Just answers.

Calypso runs on macOS, Windows, and Linux as a standalone binary. No Oracle client, no Python runtime, no dependencies of any kind. Download it, point it at your database, and get a professional migration report in minutes.

Why Calypso?

Most migration projects spend their first four to six weeks on discovery. Teams run manual queries, build spreadsheets, schedule interviews, and still end up with blind spots that come back to haunt them during implementation. Calypso compresses that entire discovery phase into a single automated assessment.

• One tool covers everything — host, instance, schema, storage, performance, replication, licensing, and target compatibility
• 16 migration targets assessed — including Oracle Cloud, Google Cloud, Azure, AWS, Snowflake, and PostgreSQL
• AI-powered recommendations — built-in integration with Claude, Gemini, and OpenAI delivers executive-level guidance tailored to your database
• Professional reports ready to share — HTML for stakeholders, JSON for automation, TXT for quick reference

How It Works

Three steps. No complexity.

1. Connect. Point Calypso at any Oracle database — version 11g through 23ai. It only needs read-only access (SELECT_CATALOG_ROLE). No agents, no installs, no risk to your production environment.

2. Assess. Calypso runs 281 queries across every dimension of your database. It analyzes configuration, performance baselines, storage trends, schema objects, replication readiness, licensing, and target platform compatibility — all automatically.

3. Deliver. Receive a professional, branded report organized by category. Hand it to your migration team, share it with stakeholders, or feed it into your planning process. Everything you need is in one document.

Where Can You Migrate?

Calypso assesses migration readiness across 16 target platforms spanning every major cloud provider and several additional platforms. Each target gets its own compatibility scoring, data type mapping, feature gap analysis, and migration method recommendations.

Oracle’s multicloud strategy means Oracle Database services now run natively inside Google Cloud, Azure, and AWS data centers. Calypso covers every one of these Oracle@ targets — so whether your destination is Oracle Database@Google Cloud, Oracle Database@Azure, or Oracle Database@AWS, you get a clear migration assessment before you commit.

Oracle-to-Oracle Migrations

Upgrade, Consolidate, or Move to OCI with Confidence

Not every migration means leaving Oracle. Upgrading from 11g to 19c, consolidating into multitenant, or moving to Oracle Cloud Infrastructure are some of the most common — and most misunderstood — migration projects. Calypso gives you the full picture before you start.

What You Get:

• License audit — see exactly which Oracle features and options are in use, which are historically used, and which you’re paying for but don’t need
• Migration method scoring — Calypso evaluates your database and recommends Data Pump, GoldenGate, or a combination based on your specific characteristics
• Parameter validation — flags restricted, deprecated, and hidden parameters that could cause problems after migration
• Multitenant awareness — full CDB/PDB support for Oracle 12c+ so you can plan container strategies with clarity

Oracle-to-Snowflake Migrations

The Deepest Pre-Migration Analysis Available

Snowflake is a first-class migration target in Calypso — not a checkbox. With 19 dedicated validation queries, Calypso maps every dimension of your Oracle database against Snowflake’s architecture so you know exactly what’s involved before the project begins.

What You Get:

• Schema compatibility — 35 data type mappings, 33 syntax alternatives, 16 DBMS package alternatives, and 24 feature compatibility entries
• Workload sizing — analyzes Oracle CPU, SGA, active sessions, and I/O profiles to recommend the right Snowflake warehouse size
• Dependency mapping — identifies upstream sources and downstream consumers (applications, scheduler jobs, database links, integrations) with Snowflake replacement recommendations
• Code conversion analysis — detects 18+ Oracle-specific function patterns in PL/SQL and provides Snowflake-equivalent alternatives

Oracle-to-Google Cloud Migrations

Multicloud, Bare Metal, or Full Re-Platform

Google Cloud offers multiple paths for Oracle workloads, and Calypso covers all of them. Whether you’re targeting Oracle Database@Google Cloud (Oracle Exadata and Autonomous Database running in GCP data centers), Bare Metal Solution, Compute Engine, or a full re-platform to AlloyDB or BigQuery, Calypso assesses your readiness for each target.

What You Get:

• Target-specific compatibility scoring for every GCP option — from lift-and-shift to full re-platform
• Feature gap analysis that shows what works natively, what needs conversion, and what requires a workaround
• Sizing recommendations to help right-size your GCP infrastructure from day one
• AI-powered analysis using Google’s own Gemini models for context-aware migration guidance

Oracle Database@Google Cloud is expanding rapidly — new regions, new services, and a new partner program are making it easier than ever to run Oracle in GCP. Calypso ensures you start that journey with complete visibility into what you’re migrating.
