# 升级/迁移 Windows 节点
## 一、准备工作
**必须先导出原节点私钥！！！**
私钥导出教程，[点击前往](/kai-shi/jie-dian-yun-xing/windows/zai-windows-shang-yun-xing-jie-dian.md#h65dh)
准备好私钥，用于导入节点账号。
## 二、停止原节点
如果是迁移节点，可跳过该步骤。
Windows 中退出原节点的运行中断即可。
## 三、启动新节点
将下载好的压缩包解压覆盖上个版本的文件即可；
注：
* 若无需启动矿池，可以删除最后的参数：--stratum-address 0.0.0.0 --stratum-port 9880；
* \--net main：指定主网，测试网可写 barnard；
```powershell
starcoin.exe --net main ^
--disable-metrics true ^
--miner-thread 0 ^
--node-name starcoin-main ^
--data-dir C:\starcoin\data ^
--logger-disable-file true ^
--stratum-address 0.0.0.0 --stratum-port 9880
```
操作截图：
## 四、导入私钥并设为默认账号
连接控制台（前提：节点运行中）：
```powershell
starcoin.exe -c \\.\pipe\starcoin\main\starcoin.ipc console
```
检查新版本默认账号：
```
account default
```
截图如下：
如果上面的账号是自己之前的，就结束了，如果账号不对，请导入私钥，并设置为默认账号。
导入私钥：
```
% account import -i 私钥
```
设置为默认账号：
```
% account default 私钥对应的账号
```
