Pre-17.5.0 UEFI-enabled GCP images cannot boot into upgraded versions, causing upgrade failures.
- A pre-17.5.0 GCP image with 2 boot locations is in use. - The UEFI_COMPATIBLE flag is set on the image. - TMOS is installed into the second boot location
Deploy another instance of BIG-IP VE using the correct image for the desired target TMOS software version. The original configuration can then be restored from UCS backup. To avoid facing the same issue on future upgrades, only set the UEFI_COMPATIBLE flag on the image if it is currently running TMOS v17.5.0 or higher.
