You run the crsetup.sh --check command to upgrade Dell PowerProtect Cyber Recovery software by using the precheck option.
crsetup.sh --check
What initial check does the update precheck perform?
The crsetup.sh --check precheck utility for Dell PowerProtect Cyber Recovery begins its validation sequence by confirming that the version currently installed on the system is compatible with the target upgrade version, since attempting an unsupported version jump (skipping required intermediate releases) would invalidate the rest of the upgrade before any other environment checks are meaningful. Only after this compatibility gate passes does the precheck proceed to validate other prerequisites for the upgrade.
