upgrade seata 1.5.2 to 2.4 #7573

Is it possible to perform a smooth upgrade from Seata version 1.5.2 to version 2.4? Will the client using 1.5.2 be compatible with the server using 2.4? What should I pay attention to when upgrading? |

我也看了这个文档，发现有这个兼容性事项需要注意
但是升级的话 肯定要升级服务端到2.4，此时客户端如果仍然是 1.5.2，这时分布式事务是否会受影响呢？ |

This is backward compatible, but the TCC changes are on the client side, so simply upgrading the server alone cannot resolve this issue. |

也就是说如果升级服务端到2.4，客户端使用1.5.2版本 API也是兼容的；但是如果客户端也升级到了2.4版本，那么就需要将注解修饰在实现类上？ |

If you are using the @LocalTCC annotation, it must still be placed in the implementation class. If @LocalTCC is not used and the provider is Dubbo or SOFA-RPC, the consumer side will bypass the proxy. In this case, only the provider will handle branch registration and the two-phase commit or rollback. |
