F5 working as IdP & SP's are in the cloud (SaaS Model)

[Sajid]

I am using Digicert certificate for b/w IdP and SP. Soon digicert certificate will expire. Do we have to upload to all SP's (around 15).

Is there any easy way to do?

You need to update all of the SPs. Create a clone IdP, export the metadata and send it to the SPs to be updated.
