我必须在两个Neo4j数据库之间移动数据。其中一个是较旧的(2.1.8),而另一个是2.3.0。 我试过的是这个,但你也可以在输出中看到有什么不对。在Neo4j数据库之间移动数据
/home/adam/neo4j-community-2.1.8/bin/neo4j-shell -path /home/adam/neo4j_bak9/ -c "dump" | /home/adam/neo4j-community-2.3.0/bin/neo4j-shell -file -

ERROR (-v for expanded information):
Transaction was marked as successful, but unable to commit transaction so rolled back.
-host Domain name or IP of host to connect to (default: localhost)
-port Port of host to connect to (default: 1337)
-name RMI name, i.e. rmi://<host>:<port>/<name> (default: shell)
-pid Process ID to connect to
-c Command line to execute. After executing it the shell exits
-file File containing commands to execute, or '-' to read from stdin. After executing it the shell exits
-readonly Connect in readonly mode (only for connecting with -path)
-path Points to a neo4j db path so that a local server can be started there
-config Points to a config file when starting a local server
Example arguments for remote:
-port 1337
-host 192.168.1.234 -port 1337 -name shell
-host localhost -readonly
...or no arguments for default values
Example arguments for local:
-path /path/to/db
-path /path/to/db -config /path/to/neo4j.config
-path /path/to/db -readonly
它看起来是Neo4j的是生产的语法,不能被新版本读取。我做错了什么或者这是一个错误?
前段时间我创建了一个脚本,关心下载本身并执行升级:http://blog.armbruster-it.de/2012/06/upgrading-an-old-neo4j-database-using- groovy/ –
我写了一个可以正确导出的shell扩展:https://github.com/jexp/neo4j-shell-tools#cypher-export –
将旧数据库复制到新位置并设置allow_store_upgrade的想法是我的第一个。但是,这有问题。我通过2.1.8 - > 2.2.6 - > 2.3.0解决了它。不过,这是一件好事,一种简单的方法来转储数据库,然后加载它,而无需其他工具。原创想法看起来很有希很遗憾,由于这个小问题,这是不可能的。我希望它至少兼容2.3.0 <-> 2.3.0。 – Cob
