2. Migration Planning

2.1 Database Migration Procedures

Pre-Migration Assessment

#!/bin/bash
echo "=== HeliosDB Migration Assessment ==="

# 1. Source database analysis
echo "1. Analyzing source database..."
psql -h $SOURCE_HOST -U $SOURCE_USER -d $SOURCE_DB -c "
  SELECT
    schemaname,
    tablename,
    pg_size_pretty(pg_total_relation_size(schemaname||'.'||tablename)) as size,
    n_live_tup as row_count
  FROM pg_stat_user_tables
  ORDER BY pg_total_relation_size(schemaname||'.'||tablename) DESC
  LIMIT 20;
"

# 2. Schema compatibility check
echo "2. Checking schema compatibility..."
./scripts/check-compatibility.sh $SOURCE_DB

# 3. Data volume estimation
echo "3. Estimating migration time..."
TOTAL_SIZE=$(psql -h $SOURCE_HOST -U $SOURCE_USER -d $SOURCE_DB -t -c "
  SELECT pg_database_size('$SOURCE_DB');
")
MIGRATION_HOURS=$((TOTAL_SIZE / 1024 / 1024 / 1024 / 10))  # ~10GB/hour
echo "Estimated migration time: $MIGRATION_HOURS hours"

# 4. Dependencies check
echo "4. Checking dependencies..."
./scripts/check-dependencies.sh $SOURCE_DB

echo "Assessment complete. Review results before proceeding."

Downtime: 1-4 hours
Data loss: None
Complexity: Low

Type 2: Online Migration (Near-zero downtime)

Use for: Production databases
Downtime: <1 minute (cutover only)
Data loss: None
Complexity: Medium

Type 3: Phased Migration (Gradual rollout)

Use for: Large, complex databases
Downtime: None
Data loss: None
Complexity: High

2.2 Zero-Downtime Migration

Migration Phases

Phase 1: Preparation (Day 1-3)
├─ Schema compatibility verification
├─ Test migration in staging
├─ Performance baseline capture
└─ Rollback procedures tested

Phase 2: Initial Sync (Day 4-7)
├─ Full database copy (async)
├─ Index creation (parallel)
├─ Data verification
└─ Delta sync setup

Phase 3: Delta Sync (Day 8-14)
├─ Continuous replication
├─ Lag monitoring (<5 min)
├─ Data consistency checks
└─ Application testing

Phase 4: Cutover (Day 15)
├─ Final delta sync (5-10 min)
├─ Application redirect (30 sec)
├─ Verification (5 min)
└─ Monitoring (24 hours)

Phase 5: Decommission (Day 16-30)
├─ Old database kept in read-only
├─ Parallel running for 2 weeks
├─ Final verification
└─ Old database decommission

4.3 Scaling Thresholds

When to Scale Up (Add Nodes)

CPU Threshold:

Sustained >70% CPU for 1 hour
Action: Add 2-4 data nodes

Memory Threshold:

Sustained >80% memory for 30 minutes
Action: Add 2-4 data nodes or upgrade instance size

Storage Threshold:

75% disk usage
Action: Add storage or add nodes

Latency Threshold:

P99 latency >50ms for 10 minutes
Action: Add nodes or optimize queries

Throughput Threshold:

Approaching 80% of capacity
Action: Add nodes proactively

When to Scale Down (Remove Nodes)

Low Utilization:

<30% CPU for 7 days
<40% memory for 7 days
Action: Consider removing 20% of nodes

Cost Optimization:

Review quarterly
Remove underutilized nodes
Consolidate small instances to larger ones
