我在 Neo4j 企业版和社区版之间切换时遇到问题。由于我无法进行 graphml 导入，我切换到可以导入 graphml 数据库的企业版。完成后，我试图打开在企业版中创建的数据库文件社区版本它给出错误。

  org.neo4j.server.database.LifeCycleManagingDatabase was succesfully initialized but failed to start

是否可以在社区中打开在企业版中创建的数据库。我在这里做错了什么？

请找到我从 java 打开数据库时遇到的错误。

最好有相同版本的 Neo4j 社区和企业。

如果您的企业版本较旧，那么社区。我建议更改以下属性以更新数据存储

conf/neo4j.properties 

allow_store_upgrade=true

除了@MicTech 所说的，您不能降级数据存储。Neo4j 支持升级。因此，当从社区迁移到企业时，企业变体需要是相同版本或更新版本。

在进行商店升级之前，使用旧版本彻底关闭至关重要。

根据他们关于 Ubuntu 和 Debian 的文档，您可以对Neo4j 2.3.1进行如下升级

Neo4j Debian 存储库可以在 Debian 或 Ubuntu 上使用。

要使用存储库，请执行以下步骤：

wget -O - https://debian.neo4j.org/neotechnology.gpg.key | sudo apt-key add - echo 'deb http://debian.neo4j.org/repo stable/' /tmp/neo4j.list sudo mv /tmp/neo4j.list /etc/apt/sources.list.d sudo apt-获取更新

安装 Neo4j 安装最新的 Neo4j 社区版：

sudo apt-get 安装 neo4j

安装最新的 Neo4j 企业版：

sudo apt-get install neo4j-enterprise

安装过程将指导您完成升级
