Huawei Cloud RDS Single-to-HA Conversion

Overview

Use the hcloud (KooCLI) command-line tool to convert a Huawei Cloud RDS for MySQL single instance to a primary/standby (HA) instance, with strict precondition checks, an optional pre-conversion manual backup, conversion task polling, and result verification. This conversion is irreversible, so the workflow requires explicit user confirmation before executing the change step, and presents the risks and impact of the conversion up front.

Prerequisites

• Python >= 3.9
• hcloud >= 7.2.2 with AKSK authentication configured (hcloud configure init)
• The target RDS for MySQL instance MUST currently be a Single instance in ACTIVE state
