Yes you can, you don't need to re-register clients as long as new server has the same fqdn & the same key, here what I use to work with DB:
#Backup_DB export PGPASSWORD="rhnpw" pg_dump --username=rhnuser -w rhnschema > /tmp/db.sql #Restore createdb -E UTF8 rhnschema createlang plpgsql rhnschema createlang pltclu rhnschema yes $PGPASSWORD | createuser -P -sDR rhnuser psql -e -d rhnschema -f /tmp/db.sql So you just need to follow this man https://fedorahosted.org/spacewalk/wiki/SpacewalkBackup Save all directories, install sp on new server & then copy & restore db, don't forget to use the same postgres version, or you'll get problems.
