我正在通过AWS上的Docker卷在Neo4j v3.5.11 CE上运行一个数据库。我想升级到4.4.9，所以我创建了一个的tar/graph.db并将其带回我的开发箱。我提取到/var/lib/neo4j/data/databases。我把它安装到neo4j v3.5.11容器上，它开始运行得很好。我可以通过localhost:7474查看所有数据。
接下来，我尝试通过：安装到neo4j v4.4.0
docker run -d -p 7474:7474 -p 7687:7687 -v /var/lib/neo4j/data:/var/lib/neo4j/data -v /var/lib/neo4j/plugins:/plugins -v /var/lib/neo4j/logs:/var/log/neo4j -e NEO4J_AUTH=none -e NEO4J_dbms_allow__upgrade=true --name neo4j neo4j:4.0.0
Neo4j失败："Transaction logs contains entries with prefix 2, and the highest supported prefix is 1. This indicates that the log files originates from a newer version of neo4j."这很奇怪，因为它是从3.5.5升级而来的，一直在3.5.11-上运行，从未被更新的版本接触过。

我尝试了几件事：
1.(删除事务日志：sudo rm graph.db/neostore.transaction.db.*即使目录中没有事务日志，也会抛出完全相同的事务日志错误；
2.(通过将此添加到运行命令中尝试数据库恢复：-e NEO4J_unsupported_dbms_tx__log_fail__on__corrupted__log__files=false此操作在"Unknown store version 'SF4.3.0'":中失败

任何想法都值得赞赏！谢谢
删除事务日志从来都不是一个好主意。您要做的是添加一个环境变量：
dbms.allow_upgrade=true
然后，它应该像文档中所说的那样工作，您可以更新最新的3.5到4.0.0 Neo4j版本。
