Is there a recommended/standard approach to handling blue/green deployments for Sitecore Commerce services?
Our Sitecore app services are hosted on Azure and we are able to do zero-downtime deployments, only if commerce is unchanged. If commerce has to be updated, then there needs to be some downtime for the one of the Sitecore CD environments.
Is there a way to temporarily switch to using the Authoring environment while upgrading Shops?
If not, what/how many services need to be duplicated?
