Hi Praveen,
You can find instructions on applying hotfixes in the documentation for the hotfix. Most use the same process, but it is recommended to review the documentation for the specific hotfix before applying to confirm no other changes may be needed.
Hotfix documentation can be found here:
CA Privileged Access Manager Hotfixes Home - CA Privileged Access Manager Hotfixes - CA Technologies Documentation
Similarly you will find instructions on applying Maitnence patches in their release notes Upgrading section, here is one example:
Upgrading - CA Privileged Access Manager - 2.8.3 - CA Technologies Documentation
