How do you keep user.config settings across different assembly versions in .net? 如何在.net中的不同程序集版本中保留user.config设置？
seems to be what you are looking for. 似乎是你在寻找什么。
So use Upgrade, UpgradeRequired=true or false, and Save : it would be quite long to explain all cases, but it is in fact quite easy to figure out what to do. 因此，使用Upgrade，UpgradeRequired = true或false，并保存：解释所有情况将会很长，但实际上很容易弄清楚要做什么。

Looks like there is no way to do this other than doing it manually yourself. 看起来除了自己动手做之外别无他法。 So after a successful upgrade, you can remove the old version manually using file system methods. 因此，升级成功后，您可以使用文件系统方法手动删除旧版本。
