Module migration 

Index migration utilities

This module provides tools for migrating data between different index types and configurations, including upgrading from in-memory to disk-based indices, applying quantization, and changing index parameters.

Features

• Index Type Migration: Convert between HNSW, DiskANN, and quantized indices
• Configuration Updates: Change index parameters with data preservation
• Batch Migration: Efficient bulk data transfer
• Progress Tracking: Monitor migration progress

Example

use ipfrs_semantic::migration::{IndexMigration, MigrationConfig};
use ipfrs_semantic::hnsw::VectorIndex;

// Create a migration plan
let config = MigrationConfig {
    batch_size: 1000,
    verify_after_migration: true,
    ..Default::default()
};

let migration = IndexMigration::new(config);

// Migration would be performed here
// migration.migrate(source_index, target_index)?;
