We have a distributed serach environment and we are using deployer to push ITSI app to all SH's. On deployer node in etc/shcluster/apps we have ITSI App components.
While upgrading from v2.6.1 to v3.1.1 do we need to copy all the extracted files of .spl to splunk_home/etc/shcluster/apps ? OR only SA-ITOA app has to be copied? Can someone guide me how to proceed the documentation is not clear me.
