Migration Assessment — Executive Summary
Date: {{ date }}
Skill: amazon-opensearch-service v{{ skill_version }}
Source: {{ fingerprint.source_engine | default:'unknown' }} {{ fingerprint.version | default:'(version not provided)' }} ({{ fingerprint.summary.total_gb | default:'?' }} GB / {{ fingerprint.summary.index_count | default:'?' }} indexes)
Target: Amazon OpenSearch {{ migration_path.decision_inputs.target | default:'Service' }} ({{ sizing.region | default:'us-east-1' }})
TL;DR
- Recommendation: Proceed with {{ migration_path.recommended }} for the data movement.
- Readiness Score: {{ readiness.overall_score }}/100 ({{ readiness.tier }})
- Sizing inputs for Pricing Calculator: see Sizing section in the full report; plug values into https://calculator.aws for monthly cost.
- This skill MUST NOT estimate dollar costs because pricing changes monthly and account-specific RI / Savings Plan / EDP discounts are out of scope — those route to https://calculator.aws.
Why migrate
The current {{ fingerprint.source_engine }} stack has known migration specifics and risk-blockers that the assessment surfaces. Amazon OpenSearch Service / Serverless NextGen eliminates self-managed infrastructure, provides managed snapshots, multi-AZ HA, and access to the OpenSearch ecosystem (Anomaly Detection, Alerting, ISM, Security Analytics). Specifically for {{ fingerprint.source_engine }} sources, AWS publishes a prescriptive guide that informs every step of this assessment.
Three items to flag
Frame items with a known remediation as migration specifics (the path already handles them); reserve risk framing for items with no clean fix, capacity-plan implications, or target-choice constraints.
- Add the top risk-blocker (BLOCKING with no clean remediation) here
- Add the top migration specific (HIGH item the path already handles) OR the second risk-blocker, whichever has higher impact
- Add the top operational/cost item here — frame per its lane
Decision
| Tier | Action |
|---|---|
| GREEN (≥80) | You MUST proceed; assign owner, target date |
| YELLOW (60–79) | You MUST PoC + spike on the lowest-scoring dimension before committing |
| RED (<60) | You MUST NOT commit because the readiness score is below the safe-migration threshold; revisit the weakest dimension first |

Citations
For the canonical retrieval recipe (every URL the skill ever cites — AWS Prescriptive Guidance for Solr → OpenSearch, OpenSearch Service pricing, Migration Assistant for Amazon OpenSearch Service, sizing-domains, serverless-overview, …) see knowledge-retrieval.md. You MUST cite the live URLs you actually retrieved here, with retrieval timestamps; https://calculator.aws is the cost handoff.
