Migrating a failover IP

Find out how to migrate a failover IP address to another instance

Last updated 9th April 2020

Objective

Being able to migrate IP addresses generally limits or removes the possibility that your service becomes unavailable. For example, you can effectively update a whole website to a new version or you can keep a replicated server active while running maintenance or installing updates on your production server.

This guide explains how to migrate a failover IP from one OVHcloud Public Cloud instance to another.

Prerequisites

Instructions

First, log in to the OVHcloud Control Panel, go to the Public Cloud section and select the Public Cloud service concerned. Then, select Failover IP in the “Network” section. In our example, a failover IP is routed to "Instance_A" and we want to redirect it towards "Instance_B".

The failover IP can be configured on the destination server before or after carrying out the migration. If it was preconfigured, it will begin to respond as soon as the routing operation is completed.
