# Elasticsearch -> Manticore Search data migration tool

Let us introduce a new tool that can help you migrate your data from Elasticsearch to Manticore Search - https://github.com/manticoresoftware/es2ms .

This tool automates copying data from [Elasticsearch](https://www.elastic.co/elasticsearch/) to [Manticore Search](https://manticoresearch.com/)

### [](https://github.com/manticoresoftware/es2ms#requirements)Requirements
1. Elasticsearch dump tool : <https://github.com/elasticsearch-dump/elasticsearch-dump>
2. Elasticsearch and Manticore PHP clients

```bash
composer update
```

Migrate all indexes:


```bash

```
Migrate certain indexes:


```bash
php migrator.php  --elasticsearch.host=my.domain.com --elasticsearch.port=9200 --indexes=index1,index2

```
