An LTM device is running BIG-IP v10.2.0 software. The LTM Specialist is tasked with upgrading the LTM device to BIG-IP v11.2.0 HF1. The LTM Specialist starts the upgrade process by selecting the uploaded Hotfix and installing to an unused volume. After 10 minutes, the LTM Specialist checks the status of the upgrade process and notices that the process is stalled at 0%.
What should the LTM Specialist verify?
To upgrade an LTM device to a new software version, the base software version must exist on the device before applying a hotfix. If the base version is not present or if there are multiple versions causing a conflict, the system cannot proceed with the upgrade, resulting in the process stalling at 0%.

B - Correct. While installing hotfix image without installing main image, the system needs to install main image prior to hotfix installation. The BIG-IP tries to find if any ISO file of the main image does exist in /shared/images directory. If there are two or more ISO image file for the same main version exist on the disk, the system is not able to select which one to use and upgrade process stuck https://support.f5.com/csp/article/K16905067
