I have a multi server sharepoint farm (2 apps, 2 wfe, 1 search/crawl, 2 dbs). It's time to renew the ssl certs for 3 web applications (not central admin). Do I need to just 1 CSR from any sharepoint server or from all sharepoint servers or create 2 separate CSR from 2 WFE Servers?
Same question when I get the cert from vendor. Do I just apply them to WFE iis at the web application level? Or all SP servers?
Can someone please help me or point me to a good article or video?
