Question

我在neo4j企业版和社区版之间切换问题。由于我无法进行graphml导入，我切换到企业，我可以导入graphml数据库。一旦我完成，我试图打开创建的数据库文件社区版中的企业版本给出错误。

  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？

请查看我从java打开数据库时遇到的错误。

Answer 1

拥有相同版本的Neo4j社区和企业会更好。

如果您的企业版本比社区旧。我建议更改以下属性以获取更新数据存储区

conf / neo4j.properties

allow_store_upgrade=true

Answer 2

除了@MicTech所说的，你不能降级数据存储。 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，使用旧版本进行干净关机至关重要。

Answer 3

根据他们关于Ubuntu和Debian的文档，您可以按照以下步骤进行升级， Neo4j 2.3.1
