Upgrading databases using the CDP CLI

It is possible to upgrade from Azure Single Server to Azure Flexible Server using the CDP CLI. You can use the regular Cloudera Data Hub and Data Lake database upgrade commands to do this. The upgade to PostgreSQL 14 automatically upgrades the database from Single Server to Flexible Server.
