将 NOM 持久化数据库迁移到 5.x
如果要迁移 **Neo4j Ops Manager 作为持久化存储使用过的** 4.4 数据库到 5.x 数据库，请按照文档中概述的 Neo4j 迁移正常步骤操作。
在遵循迁移过程之前或之后，请在持久化数据库上执行以下查询。您可以通过 Cypher-Shell 或 Neo4j 浏览器连接到它。如果不运行此查询，Neo4j Ops Manager 服务器可能无法启动。
|
仅当您将 Neo4j 4.4 版本的现有持久化数据库迁移到 Neo4j 5.x 时，才运行以下查询。 不要更改此查询，因为它可能会对 Ops Manager 产生负面影响，例如无法启动。 除了运行此查询之外，不要进一步修改持久化数据库的内容。 |
