Depending on your scenario:
- do you use Cloudera Manager to manage CDH?
- do you also want to move Sentry Database?
If you use CM and do not need to move the Sentry database, then you can simply delete the current Sentry and then add a new one which can be configured to read from the same DB.
Don't forget to backup Sentry DB first just in case.
