Copy Database on Neo4J Desktop from One Machine to Another


I am new to Neo4J. I am using Neo4J Desktop (1.4.1), on Windows 10 with Google Chrome (Version 88.0.4324.150 (Official Build) (64-bit)).
I have created a database on my old machine and would like to copy it to my new machine. I tried to use neo4j-admin command, but always encountered error message like this, although I have installed Java 11 already:

Please help..thanks a lot..

Which Neo4j version is running on your old machine?

from the screenshot it appears you ran neo4j-admin --database= .... .... ..... but you have not provided any command to run, i.e. neo4j-admin copy
