I can't copy a database to another database

Hello,
I would like to copy database to another database
steps I do

  • create a new local dbms "Test1" with user name and password
  • copy database (that want to copy) to dbms folder.
  • open terminal on my local dbms (test1)
  • run command bin\neo4j-admin copy --from-database=grid --to-database=neo4j --force

error "there was a problem during copy "

neo4j-admin copy works on offline databases only. Is your Neo4j instance terminated when trying to do that? Because if the process is running and the neo4j database you're trying to copy to is online, this should fail.
