Azure Services Plan from S1 to D1. What happens to installed SSLs?

Warwick Foster 1

HI Folks,

I want to mothball a server and want to know what will happen when I shift it from an S1 server to a D1 server. I have Domains and SSL's installed what will happen to them when I downgrade? Are they removed or are the switched off and left in place?

Thanks

Warwick

Hello @Warwick Foster

You are using App Service Plan S1 with Custom domain and SSL features.
App Service Plan D1 also supports Custom domain feature but no support for SSL feature

So, if you switch App Service Plan from S1 to D1, Custom domain will be preserved and SSL will be unavailable and removed.

@Warwick Foster to add to the great response from @Andriy Bilous you will need to remove your SSL binding before scaling down. If you attempt to scale down to D1 from S1, you will receive a warning message saying, "Cannot update the site with hostname 'contoso.net' because its current SSL configuration 'SNI enabled' is not allowed in the target compute mode. Allowed SSL configuration is 'Disabled'."

When you scale your app back up to S1 at a later date, you will need to ensure you add back the SSL binding.

Also, keep in mind that your domain will sit without any SSL support, which will often cause warnings in modern browsers. Just an FYI.
