Is it possible to clean install TOS 6?

[V8Triker]

This may seem stupid question, but all the posts in the "Update Notice" section suggest that the only way to get to TOS 6 is via TOS 5.

I am currently on 4.2.44.
I appreciate TOS 5 is a complete format and re-install, which is not really a problem.
But, copying my data back on is going to be time consuming. Around 4.5Tb, via USB

So, is it possible to do a vanilla install of TOS 6?

Reading through the updat posts, it would seem I have do the following:
Format and install 5.0.120 -> 5.0.176 -> 5.1.24 -> 5.1.40 -> 5.1.145 -> 6.0.229 -> 6.0.530
NOTE: I can not even find a 5.1.145

After backing up your data to other devices, are you going to format the disks and install TOS6 directly?
