I installed on a new VM the new HCS 8.0 with TuningManager etc. I started migrating the database from old 7.4
./hcmdsdbtrans -export -workpath /tmp/hirdb/tmp -file /tmp/hirdb/livedb -auto
after this I tried to import to 8.0
./hcmds64dbtrans -import -workpath /tmp/hirdb/tmp/ -file /tmp/hirdb/livedb -type ALL -auto
KAPM05900-I The hcmds64dbtrans command has started.
KAPM05935-I The archive file will now be extracted.
KAPM05936-I The archive file has been extracted.
KAPM05916-E An attempt was made to register secondary server data into the primary server.
But the old 7.4 not a cluster. Any idea? I'm really stuck in this point...
