将 neo4j 数据库从 2.0.1 升级到 2.1.3 失败

我正在尝试将在 Windows 上运行的 Neo4j 商店从 2.0.1 升级到 2.1.3。

我所做的，从工作 2.0.1 开始。环境，如下：

• .\2.0.1\bin\neo4jinstall.bat 删除
• xcopy .\2.0.1\data\findsi.graphdb .\2.1.3\data\findsi.graphdb
• .\2.1.3\bin\neo4jinstall.bat 安装

这将失败并显示以下消息：Detected incorrectly shut down database, performing recovery..

我的（2.1.3）messages.log 文件告诉我这一点：

现在，如果我这样做.\2.0.1\bin\neo4jinstall.bat install尽管是旧版本，但一切都恢复正常。我的猜测是，它与实际的数据库无关。

正如文档所述，我通过设置进行了显式升级设置allow_store_upgrade=true在我的2.1.3环境中。

我不愿意手动更改数据库文件夹中的内容，但我确实需要升级，因为它解决了我一直在努力解决的一些性能问题。

可能有2个问题

1. 你做了 xcopy /r （即递归地）吗？
2. windows 通过硬终止来终止服务，即不让它正确关闭

因此，在 2.0.1 上，启动时它总是必须执行恢复，而 2.0.3 拒绝在非完全关闭的数据库上启动。

您可以通过使用以下命令启动 2.0.1 数据库一次来缓解这个问题

bin\Neo4jShell.bat -path data\findsi.graphdb

与你的数据库，然后干净地停止它quit在复制之前。
