cannot see my new environment for OP manager

i installed OP manager in another linux box and wanted to migrate my environment(all configs) from my old box to my new one. i copied the files

 /opt/ManageEngine/OpManager/users
/opt/ManageEngine/OpManager/conf
/opt/ManageEngine/OpManager/mysql/data

from the old to new box but when i log into OP Manager hosted in the new box, nothing had been migrated. Kindly assist. am stuck :-(
