Other PSC members should be able to add to their insights to my response. Sincerely, Pawan Accepted Solution Posted: 2 years agovinas PEGA replied to AKSHAYHello Akshay, Adding to Pawan's response, from a Pega perspective, it's unlikely that there will be much difference in terms of performance. You can check the below link in order to get an idea how normal applications perform when migrated to Java 8. http://engineering.indeedblog.com/blog/2016/09/job-search-web-app-java-… Also, if you have TLS related integrations, you would have to keep in mind that Java 8 uses TLS 1.2 protocol by default. Thank you, Shreshta Posted: 2 years agoAKSHAY Cognizant Technology Solutions replied to vinasThanks Vinas and Pawan for your inputs. I'm verifying the parameters in our systems after upgrade.
