[rohitk1609]

Hi team,

we have multi node setup , June 2019 version, installed with database user  postgres. In latest release, as per Qlik document, database user we need to keep is qliksenserepository.  We want to know what things we need to setup of pre configure before upgrade to manage database user?

Thanks in advance.
