# 0.11.0 Migration Guide

> Migration guide for upgrading from Blnk v0.10.x to v0.11.0, covering Typesense upgrades and breaking changes.

## Overview

This migration guide covers the breaking changes introduced in Blnk v0.11.0, specifically related to Typesense/Search functionality. The main change involves upgrading the Typesense server from version 0.23.x to 0.24.x, which requires updating your Docker configuration.

***

## Breaking changes summary

* **From:** Typesense 0.23.x
* **To:** Typesense 0.24.x
* **Impact:** Breaking changes in API compatibility and schema handling

***

## Migration steps

<Steps titleSize="h3">
  <Step title="Update Docker configuration">
    Update your Typesense server version in your Docker configuration files.

    1. **For Production (`docker-compose.yaml`)**
       ```yaml theme={"system"}
       # Before (v0.10.x and lower)
       typesense:
         image: typesense/typesense:0.23.1

       # After (v0.11.0)
       typesense:
         image: typesense/typesense:0.24.0
       ```

    2. **For Development (`docker-compose.dev.yaml`)**
       ```yaml theme={"system"}
       # Before (v0.10.x and lower)
       typesense:
         image: typesense/typesense:0.23.1

       # After (v0.11.0)
       typesense:
         image: typesense/typesense:0.24.0
       ```

    3. **For Kubernetes (`infrastructure/k8s-manifests/typesense-deployment.yaml`)**
       ```yaml theme={"system"}
       # Before (v0.10.x and lower)
       containers:
         - image: typesense/typesense:0.23.1

       # After (v0.11.0)
       containers:
         - image: typesense/typesense:0.24.0
       ```
  </Step>

  <Step title="Allow automatic schema migration">
    The new version includes automatic schema migration capabilities. When you start Blnk v0.11.0, it will automatically:

    1. **Detect existing collections** in your Typesense instance.
    2. **Compare schemas** between your current collections and the latest schema definitions.
    3. **Add new fields** to existing collections without data loss.
    4. **Create missing collections** with the latest schema.

    **Collections affected:**

    * `ledgers`.
    * `balances`.
    * `transactions`.
    * `reconciliations`.
    * `identities`.
  </Step>

  <Step title="Schema improvements">
    1. **Ledgers collection:**
       * Enhanced metadata handling with object type support.
       * Improved nested field support.

    2. **Balances collection:**
       * All balance fields now use `string` type for precise decimal handling.
       * Enhanced metadata object support.
       * Improved nested field capabilities.

    3. **Transactions collection:**
       * `precise_amount` field uses `string` type for exact decimal precision.
       * Enhanced metadata object support.
       * Improved nested field capabilities.

    4. **Reconciliations collection:**
       * No breaking changes to existing fields.
       * Enhanced performance optimizations.

    5. **Identities collection:**
       * Enhanced metadata object support.
       * Improved nested field capabilities.
  </Step>

  <Step title="Start Blnk v0.11.0">
    Start your updated Blnk instance. The system will automatically handle data migration including:

    1. **Large number conversion:** Automatically converts `big.Int` values to strings for Typesense compatibility.
    2. **Metadata normalization:** Handles metadata field normalization for object schemas.
    3. **Time field normalization:** Ensures consistent timestamp formatting.

    <Check>
      No manual intervention is required for data migration - everything happens automatically.
    </Check>
  </Step>

  <Step title="Configuration compatibility">
    <Info>
      No changes to environment variables or configuration files are required. All existing configurations remain compatible.
    </Info>

    * Environment variables remain the same.
    * `blnk.json` configuration structure unchanged.
    * Search API endpoints unchanged.
    * Response formats remain compatible.

    **API Endpoints (No Changes Required):**

    ```bash theme={"system"}
    # Single collection search
    POST /search/{collection}
    ```
  </Step>
</Steps>

***

## Testing checklist

After migration, verify the following:

* Typesense server starts successfully.
* All collections are accessible.
* Search functionality works correctly.
* Data integrity is maintained.
* API endpoints respond correctly.
* No errors in application logs.

***

## Performance improvements

Blnk v0.11.0 includes several performance improvements:

1. **Enhanced search performance:** Optimized query execution.
2. **Improved memory usage:** Better resource management.
3. **Faster schema updates:** Streamlined collection management.
4. **Better error handling:** More robust error recovery.
