[Rancher] Does Rancher support migration from single node installation to high availability installation?

This document (000020445) is provided subject to the disclaimer at the end of this document.


There is currently no validated path that is officially covered by Rancher Support for any Customer starting with a single node installation and wishing to migrate to a high availability installation at a later time. Whilst there is a Rancher blog post that talks about one possible migration path, it is not covered by Rancher Support.

Where scale and performance criteria are well understood to be critical, Customers are recommended to set up Rancher in a high availability configuration, right from the outset.
Running a single node installation might lead to unrecoverable circumstances, and it is highly recommended that production clusters run in a high availability configuration.
