Hi @rashiagrawal, I suppose that you used the Readiness App to check the compatibility with the new Splunk version using only Python3 (as Splunk8.3.x), it should indicate the non compatible modules. in few words, you used in your app some python commands or scripts that you have to modify to adapt to the new python version. Then there are some other updates to do to your dashoboard (e.g. the html version). Here you can find the documentation for update: https://docs.splunk.com/Documentation/Splunk/9.0.1/Python3Migration/AboutMigration https://docs.splunk.com/Documentation/Splunk/9.0.1/Python3Migration/ChangesEnterprise Ciao.
