In this solution, we are able to change position of a single column. Is it possible to change positions of 2 or more consecutive columns in the same way ?

Hi @Sayan, From documentations: "The Cloudera Manager minor version must always be equal to or greater than the CDH minor version because older versions of Cloudera Manager may not support features in newer versions of CDH. For example, if you want to upgrade to CDH 5.4.8 you must first upgrade to Cloudera Manager 5.4 or higher." So, if you want to upgrade cdh to 5.15 first you have to upgrade Cloudera Manager to 5.15. Best regards Andrzej

@bgooley Thank you for your help. We finished the upgrade with success. After some cleanings in the cluster we started the upgrade using CM Upgrade page. We did all steps until the new parcel activation. When we tried to do next steps from CM Upgrade page we got a error box without any messages. We redeployed configuration and restarted services manually using CM. At the end we had to redeploy Oozie Shared libraries and SQL Server JDBC dirver.
