Hi Bhavin,

Take backup of the device and try to upgrade the node through cli starting from the secondary node.

Please refer this document for upgrading ISE through cli https://www.cisco.com/c/en/us/td/docs/security/ise/2-4/upgrade_guide/b_ise_upgrade_guide_24/b_ise_upgrade_guide_24_chapter_011.html
