OceanBase 0.7.2 and OcenaBase 0.8 are incompatabile. We made plenty improvements over 0.7.2, adapting to KB 0.8 API, support Backup/Restore, Monitoring, Parameters Configurattion, Logginig. Beside, OceanBase 0.8 supports new features liks dynamict ports, host network, and fixed many bugs).

We strongly suggest users to use KB 0.8 and KBCLI 0.8 to deploy Oceanbase 0.8.
