I have an AppService where the SSL Certificate is getting expired. I have the renewed certificate. Is there a way to upload this through powershell without causing outage?
Also, I intend to automate the entire process for certificate renewal and changing in AppService is this be done through Keyvault?
To upload your renewed certificate and bind it to your app service, you could use this powershell command New-AzureRmWebAppSSLBinding.
For Auto Renew App Service Certificate, you could check it in your App Service Certificate -> Auto Renew Settings -> Auto Renew App Service Certificate, if Auto Renew is on then it will be renewed automatically before it expires, the linked App Service Apps will be moved to the new certificate.

I have a Azure app service which uses Godaddy SSL certificate. And in Godaddy Auto renewal is enabled. But everytime the SSL certificate expires i have to manually download the certificate from godaddy and convert into .pfx file to upload it on azure. Is there any way to auto renew the certificate on Azure without uploading .pfx?
I have one question regarding the azure app service certificate update. I have already a certificate bound to one of the azure web apps. But this certificate is going to expire soon. I have renewed my certificate and uploaded a new version of the certificate. So now I have two different certificates in the app service certificate store.
My question is, what is the best way to switch the certificate for the web app without any downtime?

AFAIK, the best way is to turn on automatic renewal of your certificate at any time.
Choose the certificate from the App Service Certificates page.
Then select Auto Renew Settings in the left navigation.
Select ON > Save.
If you have automatic renewal enabled on, certificates will begin renewing 60 days before they expire.
Renew App Service Certificate automatically
Click Sync once the renew operation completes which automatically updates the hostname bindings for the App Service Certificate without causing any downtime to your applications.
Refer to the Renew an expiring certificate of azure app service-SSL for more information.
My Azure App service is loading a certificate from the Azure Key Vault. I have set cert as auto-renew in key vault. My appservice is loading the new certificate, whenever Keyvault renews the cert.
I know AppService keep syncing with Azure Key Vault in a background process. How does it happen when AppService finds there is a renewed certificate in Key Vault? Does appservice loads new renewed cert in the Current User and restart the AppService?
Thanks
How does it happen when AppService finds there is a renewed certificate in Key Vault?
The Web App service runs a background job that periodically (once a day ) that syncs all App Service certificate. Hence when you rotate or update a certificate, sometimes the application is still retrieving the old certificate and not the newly updated certificate. This is because the job has not run to sync the certificate resource. It will automatically update the hostname bindings for the certificate in App Service within 48 hours.
Does app service loads new renewed cert in the Current User and restart the AppService?
It will automatically updates the certificate in App Service without causing any downtime to your apps.
We are trying to set up an automatic way to update our custom certificates bound to a lot of different hostnames (custom domains) that we use on all of our web apps.
When a renewal is needed we update a new version of the certificate in our key vault on which it will automatic sync with all of the web apps that uses the certificate. This proces works fine in Azure but we still have to update the TLS/SSL bindings in the web app by hand as this will still be bound to the old certificate, even though the new certificate is synced to the web app.
Is there a workaround for this so we don't have to open every web app and change the TLS/SSL binding by hand for each hostname with the renewed certificate?
Referring to the question asked here, Azure: manually add app service certificate to key vault
Also quoting to answer given,
" App Service Certificate stores the private certificate into a user-provided Key Vault secret. When App Service Certificate is deployed into a web app, a Web Apps resource provider deploys it from the Key Vault secret that's associated with App Service Certificate.
So, when you add app service certificate to azure keyvault, you could not see anything in Certificate option. "
As I cannot see certificates in the key vault but the certificate is stored in user provided secret, but how to export it then?
