Please check the size of your current system partition. Systems running TOS 5.1 and above require an 8GB system partition.
As TOS 6 and TOS 5 use different caching mechanisms, please disable Hyper Cache before upgrading if you have it enabled.
There are two upgrade methods:
A: First upgrade to the latest version 5.1.145, then upgrade to 6.0.530.
Release notes for 6.0.530: viewtopic.php?t=6809
B: Replace the boot system on the built-in USB drive with the TOS 6-dedicated version, then directly install the latest TOS 6:
