our client want to move nexus to dedicated server which Rocky Linux 8 , I have tried to migrate but when ever i tried to start the nexus service it is saying that

“Cannot load database configuration. The database seems corrupted”

all the data transfer was done to new machine using rsync

[rsync -avz --progress sonatype-work ip:/nexus]
