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
- at least two Public Cloud instances in your OVHcloud account
- a failover IP address
- access to the OVHcloud Control Panel
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".
Click on ... next to the failover IP and select Modify associated instance.
Choose the destination server from the list by clicking the checkbox.
Confirm with Attach.
After a few seconds the Control Panel will be updated and a confirmation message will be displayed if the migration was done sucessfully.
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.
