Will the SHA1 certificates on my exiting servers remain SHA1, or will they upgrade?<br />

- When renewing existing servers - after the CA upgrade to SHA256 - will they automatically renew to a sha256 certificate?<br />
<br />
- Do templates need to upgraded is is this done automatically?

 they will remain SHA1<br />
<br />
Once CA is upgraded all the new issued certificates will be SHA2

Hi all,<br />
<br />
We use our internal CA using a SHA1 to create certificates for internal web services. We are now tasked with upgrading this to SHA2. My colleague has suggested we renew all SHA1 certificates so that nothing is set to expire within the next 12 months. We will then look to upgrade the rootCA but im concerned that once we do that all the web certificates will need to be upgraded?<br />
<br />
Can someone clarify what happens when the ROOTCA is upgraded to SHA2?<br />
<br />
It will be difficult to know whether all web services are SHA2 compatible, is there a way to create a separate SHA2 ROOT CA?

Upgrading internal RootCA to SHA2

A Web service is a method of communication between two electronic devices over a network. It is a software function provided at a network address over the Web with the service always on as in the concept of utility computing. A web service has an interface described in Web Services Description Language (WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP (Simple Object Access Protocol) messages. There are two major classes of Web services: REST-compliant web services, and Arbitrary web services.
