cloudthinker-ai Storage Migration Plan Skill
Migrate {{ data_volume }} from {{ source_storage }} to {{ target_storage }}.
Workflow
Phase 1 — Storage Assessment
CURRENT STATE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
[ ] Source: {{ source_storage }}
- Total capacity: ___
- Used capacity: {{ data_volume }}
- IOPS (current): ___
- Throughput (current): ___ MB/s
- Latency (P95): ___ms
[ ] Target: {{ target_storage }}
- Provisioned capacity: ___
- IOPS (expected): ___
- Throughput (expected): ___ MB/s
- Latency (expected): ___ms
[ ] Data classification:
- Hot data: ___ GB
- Warm data: ___ GB
- Cold data: ___ GB
[ ] File/object count: ___
Phase 2 — Migration Strategy
STRATEGY SELECTION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Transfer method (choose one):
[ ] Online copy (rsync, AWS DataSync, robocopy)
[ ] Snapshot-based (snapshot + restore)
[ ] Streaming replication
[ ] Offline transfer (AWS Snowball, physical media)
Estimated transfer time: ___
Transfer bandwidth allocated: ___ MB/s
Impact on production workload: [ ] NONE [ ] LOW [ ] MEDIUM
Migration order:
[ ] 1. Cold data first (lowest risk)
[ ] 2. Warm data
[ ] 3. Hot data (with cutover)
Phase 3 — Data Transfer
TRANSFER EXECUTION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
[ ] Initial sync started — timestamp: ___
[ ] Progress:
- Data transferred: ___ / {{ data_volume }}
- Transfer rate: ___ MB/s
- Estimated completion: ___
[ ] Incremental sync configured for delta changes
[ ] Transfer errors encountered: ___
[ ] Integrity checks during transfer:
- Checksums validated: [ ] YES
- File count matches: [ ] YES
Phase 4 — Cutover
CUTOVER EXECUTION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
[ ] Final incremental sync completed
[ ] Application downtime window (if required): ___
[ ] Mount points / storage paths updated
[ ] Application configuration updated to target storage
[ ] Application restarted and connected to target
[ ] Read/write operations verified on target
[ ] Cutover complete — timestamp: ___
Phase 5 — Validation and Cleanup
POST-MIGRATION VALIDATION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
[ ] Data integrity confirmed:
- File/object count: source ___ vs target ___
- Total size: source ___ vs target ___
- Checksum spot check: [ ] PASS [ ] FAIL
[ ] Performance benchmarks met:
- IOPS: ___ (target: ___)
- Throughput: ___ MB/s (target: ___)
- Latency: ___ms (target: ___ms)
[ ] Application performance normal
[ ] Source storage retained for ___ days (rollback window)
[ ] Source storage decommissioned — date: ___
[ ] Cost comparison: source $___ /mo vs target $___ /mo
Counter-Rationalizations
| Shortcut | Counter | Why |
|---|---|---|
| "We can skip some steps for this case" | Adapt the workflow steps, don't skip them | Skipped steps are where incidents and oversights originate |
| "The user seems to already know what to do" | Complete all workflow phases with the user | The workflow catches blind spots that experience alone misses |
| "This is a minor case, full process is overkill" | Scale the process down, don't turn it off | Minor cases become major when unstructured; the process scales, not disappears |
| "I'll fill in the details later" | Complete each section before moving on | Deferred details are forgotten; real-time capture is more accurate |
| "The template output isn't necessary" | Always produce the structured output format | Structured output enables comparison, audit trails, and handoff to other teams |
Output Format
Produce a storage migration report with:
- Migration summary (source, target, volume, timeline)
- Transfer metrics (duration, throughput, errors)
- Data integrity (counts, checksums, validation results)
- Performance comparison (IOPS, throughput, latency before vs after)
- Cost impact (monthly cost change and projected savings)
