HiveMQ Cloud Serverless retires on December 31, 2026. Migration guides, checklists and alternatives: move to the ConnectMQ Serverless or Managed Cloud MQTT Broker.
A zero-downtime HiveMQ migration keeps both brokers running while clients move. This guide shows a complete Python relay between HiveMQ Cloud and ConnectMQ, how to avoid message loops, the right wave order and how to cut over safely.
The HiveMQ Cloud Serverless deadline is December 31, 2026. This week-by-week timeline shows how to plan your migration, test a new broker, move devices in waves and finish with a safety buffer, including a compressed plan if you are starting late.
A practical, step-by-step procedure for moving devices and applications off HiveMQ Cloud Serverless before December 31, 2026: inventory your clients, map features and credentials, test a private broker, dual-run, cut over and clean up.
When HiveMQ Cloud Serverless retires, retained messages, client sessions, access credentials and permissions are permanently deleted. This guide shows how to export retained state, document credentials and rebuild everything on your new MQTT broker.
HiveMQ Cloud Serverless Free and Pay As You Go users who want the same no-servers experience can move to the ConnectMQ Cloud Serverless MQTT Broker. See the plans, limits, endpoints, built-in tools and how to get your first device connected in minutes.
HiveMQ's free Migration license gives Serverless users a self-managed Enterprise Broker with 100 connections and 100 messages per second for 12 months. Here is what that path really involves, how it compares with a managed MQTT broker, and how to decide.
Before you switch any client away from HiveMQ Cloud Serverless, work through this checklist: measure connections and message rates, plan credentials and client IDs for the new broker, and test a private managed broker with your real topics.
Production teams on HiveMQ Cloud Serverless Pay As You Go need more than a free tier. Learn how the ConnectMQ Managed Cloud MQTT Broker, with Dedicated, BYOC and Self Managed Enterprise options, gives you isolation, predictable performance and a clean migration path.
HiveMQ is retiring its Cloud Serverless Free and Pay As You Go plans on December 31, 2026. Here is what stops working, what data is deleted, what the Migration license covers, and a practical plan to move your devices to a new managed MQTT broker before the deadline.
Every client that leaves HiveMQ Cloud Serverless needs a new hostname, credentials, client ID and TLS settings. Here are before-and-after examples for ESP32 (Arduino), Python, Node.js, Node-RED and mosquitto clients, plus the mistakes that cause failed connections.
Create an account, get your broker credentials and connect your first device — no servers to install, patch or scale.
