Plan and execute cloud migrations with assessment, database migration, application refactoring, and cutover strategies across AWS, Azure, and GCP.

Includes scriptsDevOps & Cloud

AI-generated overview

Plans and executes cloud migrations with assessment, database migration, refactoring and cutover strategies across AWS, Azure and GCP.

What it does: Guides assessment of existing infrastructure, selection of migration strategies such as lift-and-shift, replatforming and refactoring, and planning of database migration and cutover. It ships reference guides on assessment, database strategies, Terraform infrastructure and a cutover validation checklist, plus a configuration validation script and a starter configuration template. The output is a migration plan and supporting configuration artifacts.
When to use it: Use when moving workloads from on-premises to cloud, consolidating cloud platforms, modernizing legacy systems, reducing data center costs, or improving scalability, availability, compliance and disaster recovery.
Requirements: Runs in an agent environment with access to the bundled reference documents and templates. It ships an executable shell script (scripts/validate-config.sh) and a YAML starter template; the script's runtime dependencies are not specified in the source.

Overview

Cloud migration planning involves assessing current infrastructure, designing migration strategies, executing migrations with minimal downtime, and validating outcomes. Support lift-and-shift, replatforming, and refactoring approaches for smooth cloud adoption.

When to Use

Moving from on-premises to cloud
Cloud platform consolidation
Legacy system modernization
Reducing data center costs
Improving scalability and availability
Meeting compliance requirements
Disaster recovery enhancement
Technology refresh initiatives

Quick Start

Minimal working example:

python

# Cloud migration assessment toolfrom enum import Enumfrom typing import Dict, List, Tuplefrom dataclasses import dataclass
class MigrationStrategy(Enum):    LIFT_AND_SHIFT = "lift_and_shift"  # Rehost    REPLATFORM = "replatform"          # Rehost with optimizations    REFACTOR = "refactor"              # Rebuild for cloud    REPURCHASE = "repurchase"          # Switch to SaaS    RETIRE = "retire"                  # Decommission
class ApplicationComplexity(Enum):    LOW = 1    MEDIUM = 2    HIGH = 3
@dataclassclass ApplicationAssessment:    name: str    complexity: ApplicationComplexity    dependencies: List[str]    estimated_effort: int  # days    business_criticality: int  # 1-10    current_costs: float  # annual// ... (see reference guides for full implementation)

Best Practices

✅ DO

Perform thorough discovery and assessment
Run parallel systems during transition
Test thoroughly before cutover
Have rollback plan ready
Monitor closely post-migration
Document all changes
Train operations team
Maintain previous systems temporarily

❌ DON'T

Rush migration without planning
Migrate without testing
Forget rollback procedures
Ignore dependencies
Skip stakeholder communication
Migrate everything at once
Forget to update documentation
