Is peopletools upgrade 8.53 to 8.56 impact on CS90 application




    Currently we are using PeopleSoft Campus Solution 90 application and People Tools 8.53. We are planning to upgrade only tools from 8.53 to 8.56, not application. Is it any impact on CS90 application if we proceed this tools upgrade. I got know from few groups that elastic search will not work in CS90 and Verity/SES search also no longer exist in CS90 after doing upgrade 8.56. Does any one has idea about this?
