+# CipherStash Migrator
+
+The CipherStash Migrator is a tool that can be used to migrate plaintext data in a database to its encrypted equivalent.
+It works inside the CipherStash Proxy Docker container and can handle different data types such as text, JSONB, integers, booleans, floats, and dates.
+By specifying the relevant columns in your table, the migrator will seamlessly encrypt the existing data and store it in designated encrypted columns.
+
+## Prerequisites
+
+- [CipherStash Proxy](PROXY.md)
+- [Have set up EQL in your database](GETTINGSTARTED.md)
+  - Ensure that the columns where data will be migrated already exist.
+
+Here’s a draft for the technical usage documentation for the CipherStash Migrator tool:
+
+## Usage
+
+The CipherStash Migrator allows you to specify key-value pairs where the key is the plaintext column, and the value is the corresponding encrypted column.
+Multiple key-value pairs can be specified, and the tool will perform a migration for each specified column.
+
+### Running the migrator
+
+You will need to SSH into the CipherStash Proxy Docker container to run the migrator.
+
+```bash
+docker exec -it eql-cipherstash-proxy bash
+```
+
+Once inside the container, you have access to the migrator tool.
+
+```bash
+cipherstash-migrator --version
+```
+
+#### Flags
+
+| Flag | Description | Required |
+| --- | --- | --- |
+| `--columns` | Specifies the plaintext columns and their corresponding encrypted columns. The format is `plaintext_column=encrypted_column`. | Yes |
+| `--table` | Specifies the table where the data will be migrated. | Yes |
+| `--database-name` | Specifies the database name. | Yes |
+| `--username` | Specifies the database username. | Yes |
+| `--password` | Specifies the database password. | Yes |
+
+#### Supported data types
+
+- Text
+- JSONB
+- Integer
+- Boolean
+- Float
+- Date
+
+### Example
+
+The following is an example of how to run the migrator with a single column:
+
+```bash
+cipherstash-migrator --columns example_column=example_column_encrypted --table examples --database-name postgres --username postgres --password postgres
+```
+
+If you require additional data types, please [raise an issue](https://github.com/cipherstash/encrypt-query-language/issues)
+
+### Running migrations with multiple columns
+
+To run a migration on multiple columns at once, specify multiple key-value pairs in the `--columns` option:
+
+```bash
+cipherstash-migrator --columns test_text=encrypted_text test_jsonb=encrypted_jsonb test_int=encrypted_int test_boolean=encrypted_boolean --table examples --database-name migrator_test --username postgres --password postgres
+```
+
+## Notes
+
+- Ensure that the corresponding encrypted columns already exist in the table before running the migration.
+- Data migration operations should be tested in a development environment before being executed in production.
