Pre-Migration Assessment

迁移前评估

Step 1: Current State Analysis

步骤1：当前状态分析

bash

undefined

bash

undefined

Document current implementation

find . -name ".ts" -o -name ".py" | xargs grep -l "ideogram" > ideogram-files.txt

Count integration points

wc -l ideogram-files.txt

Identify dependencies

npm list | grep ideogram pip freeze | grep ideogram

undefined

npm list | grep ideogram pip freeze | grep ideogram

undefined

Step 2: Data Inventory

步骤2：数据盘点

typescript

interface MigrationInventory {
  dataTypes: string[];
  recordCounts: Record<string, number>;
  dependencies: string[];
  integrationPoints: string[];
  customizations: string[];
}

async function assessIdeogramMigration(): Promise<MigrationInventory> {
  return {
    dataTypes: await getDataTypes(),
    recordCounts: await getRecordCounts(),
    dependencies: await analyzeDependencies(),
    integrationPoints: await findIntegrationPoints(),
    customizations: await documentCustomizations(),
  };
}

typescript

interface MigrationInventory {
  dataTypes: string[];
  recordCounts: Record<string, number>;
  dependencies: string[];
  integrationPoints: string[];
  customizations: string[];
}

async function assessIdeogramMigration(): Promise<MigrationInventory> {
  return {
    dataTypes: await getDataTypes(),
    recordCounts: await getRecordCounts(),
    dependencies: await analyzeDependencies(),
    integrationPoints: await findIntegrationPoints(),
    customizations: await documentCustomizations(),
  };
}

Error Handling

错误处理

Issue	Cause	Solution
Data mismatch	Transform errors	Validate transform logic
Performance drop	No caching	Add caching layer
Rollback triggered	Errors spiked	Reduce traffic percentage
Validation failed	Missing data	Check batch processing

问题	原因	解决方案
数据不匹配	转换逻辑错误	验证转换逻辑
性能下降	未配置缓存	添加缓存层
触发回滚	错误率飙升	降低流量占比
验证失败	数据缺失	检查批量处理流程
