MDMS Migration

Steps to migrate MDMS data to enable use of workbench UI v1.0

Overview

Follow the steps below to migrate the MDMS data to enable the use of Workbench UI v1.0.

Steps

1. Generate Schema

Follow the steps below to generate the schema for Workbench UI v1.0:

Clone the migration utility: Start by cloning the migration utility from this link.
Clone the MDMS Repository: Start by cloning the MDMS repository on your local machine.
Configure application.properties: Open the application.properties file in the workbench utility and configure it as follows:
- Add the hostname of the environment.
- Add the MDMS cloned folder path in the egov.mdms.conf.path.
- Add master-config.json in masters.config.url.
- Specify the output folder path for the created schema in master.schema.files.dir.
Port-forward MDMSv2 Service: Port-forward the MDMSv2 service to port 8094.
Run the Curl Command:
```
shCopy codecurl -L -X POST 'localhost:8080/mdms-migration-toolkit/schema/v1/_generate'
```
This command generates the schema and saves it in the path specified by master.schema.files.dir.

2. Update Schema

After generating the schema, you may need to update it with additional attributes:

Add x-unique Attribute: This defines unique fields in the schema.
```
"x-unique": ["description"]
```
Add x-ref-schema Attribute: Use this attribute if a field within MDMS data needs to refer to another schema.
```
"x-ref-schema": [{"fieldPath": "billingType","schemaCode": "WaterCharges.BillingType"}]
```
Set Default Value for a Field: Use the default keyword to set default values.

3. Migrate Schema

To migrate the schema, use the following curl command:

curl -L 'localhost:8080/mdms-migration-toolkit/schema/v1/_migrate' \
-H 'Content-Type: application/json' \
-d '{
  "schemaMigrationCriteria": {
    "moduleName": "PropertyTax",
    "tenantId": "pb"
  },
  "requestInfo": {
    "apiId": "asset-services",
    "ver": null,
    "ts": null,
    "action": null,
    "did": null,
    "key": null,
    "msgId": "search with from and to values",
    "authToken": "7a9fc02a-bd6e-4e42-bd43-519b9e357bae",
    "correlationId": null,
    "userInfo": {
      "id": 878483,
      "uuid": "3059806b-3059-4724-8ae1-d3f4e12686ff",
      "userName": "8080800000",
      "name": "HRMS-ADMIN-TESTING",
      "mobileNumber": "8080800000",
      "emailId": null,
      "locale": null,
      "type": "EMPLOYEE",
      "roles": [
        {
          "name": "MDMS ADMIN",
          "code": "MDMS_ADMIN",
          "tenantId": "pb"
        },
        {
          "name": "Localisation admin",
          "code": "LOC_ADMIN",
          "tenantId": "pb"
        },
        {
          "name": "Employee",
          "code": "EMPLOYEE",
          "tenantId": "pb"
        }
      ],
      "active": true,
      "tenantId": "pb",
      "permanentCity": null
    }
  }
}'

4. Migrate Data

To migrate data for a specific master/module name, use the following curl command:

curl -L 'localhost:8080/mdms-migration-toolkit/data/v1/_migrate' \
-H 'accept: */*' \
-H 'Content-Type: application/json' \
-d '{
  "masterDataMigrationCriteria": {
    "moduleName": "PropertyTax",
    "tenantId": "pb"
  },
  "requestInfo": {
    "apiId": "asset-services",
    "ver": null,
    "ts": null,
    "action": null,
    "did": null,
    "key": null,
    "msgId": "search with from and to values",
    "authToken": "7a9fc02a-bd6e-4e42-bd43-519b9e357bae",
    "correlationId": null,
    "userInfo": {
      "id": 878483,
      "uuid": "3059806b-3059-4724-8ae1-d3f4e12686ff",
      "userName": "8080800000",
      "name": "HRMS-ADMIN-TESTING",
      "mobileNumber": "8080800000",
      "emailId": null,
      "locale": null,
      "type": "EMPLOYEE",
      "roles": [
        {
          "name": "MDMS ADMIN",
          "code": "MDMS_ADMIN",
          "tenantId": "pb"
        },
        {
          "name": "Localisation admin",
          "code": "LOC_ADMIN",
          "tenantId": "pb"
        },
        {
          "name": "Employee",
          "code": "EMPLOYEE",
          "tenantId": "pb"
        }
      ],
      "active": true,
      "tenantId": "pb",
      "permanentCity": null
    }
  }

NOTE: To migrate data for a specific master/module name, use the following code changes in migrateMasterData

/**
 * This method accepts master data migration requests and triggers
 * creation of MDMS objects
 * @param masterDataMigrationRequest
 */
public void migrateMasterData(@Valid MasterDataMigrationRequest masterDataMigrationRequest) {

    // Get Master Data map
    Map<String, Map<String, JSONArray>> tenantMap = MDMSApplicationRunnerImpl.getTenantMap();

    // Get tenantId from request
    String tenantId = masterDataMigrationRequest.getMasterDataMigrationCriteria().getTenantId();

    // Build audit details for mdms objects creation
    AuditDetails auditDetails = new AuditDetails();
    RequestInfo requestInfo = masterDataMigrationRequest.getRequestInfo();
    AuditDetailsEnrichmentUtil.enrichAuditDetails(auditDetails, requestInfo, Boolean.TRUE);

    List<JSONArray> masterDataList = new ArrayList<>();

    // Check if master data is present for the incoming tenantId.
    if (tenantMap.containsKey(tenantId)) {
        tenantMap.get(tenantId).keySet().forEach(module -> {
            if (module.equals("common-masters")) {
                tenantMap.get(tenantId).get(module).keySet().forEach(master -> {
                    if (master.equals("CancelCurrentBillReasons") || master.equals("CancelReceiptReason") ||
                        master.equals("CronJobAPIConfig") || master.equals("Department") || master.equals("Designation") ||
                        master.equals("IdProof") || master.equals("UsageCategory") || master.equals("OwnerType") ||
                        master.equals("VehicleType") || master.equals("UOM") || master.equals("StructureType") ||
                        master.equals("TablePaginationOptions")) {
                        // Get master data array for current module and master
                        JSONArray masterDataJSONArray = MDMSApplicationRunnerImpl
                                .getJSONArray(tenantMap.get(tenantId)
                                .get(module)
                                .get(master));
                        masterDataList.add(masterDataJSONArray);
                    }
                });
            }
        });
    }
}
