As per the upgrade instructions:
Make sure your apps are compatible with the new version, so they keep working after the upgrade. You'll need to disable all incompatible apps as they might affect the upgrade.
But I can't find Manage apps option by going to settings icon on Jira 7.6.
As I'm updating Jira from 7.6 to 8.4 is there any other ways to check Jira app compatibility.
