I maintained a Design with a 364 version history.
This was a totally developed design with full CAM production manufacturing.
Since this project was developed starting before what became known as Rule Number 1 in reference to components, I wanted to move forward with converting every body and associated Sketches, etc. into individual components.
I Saved the design as a new name. ( I did mange to eventually make the transition although Fusion was unable to unravel some of the linkages it made that I didn't have access to and had to redo a few components from new Sketches. This of course, wreaked havoc with CAM setup as well. and that process took a couple hundred additional version history entries for the new design.)
Not wanting to confuse designs, i decided to rename the first Design with the 364 version history. I didn't think anything of it as I received no warning errors or any indication that I was going to lose the first 363 versions of that design, but that is what appears to have happened as the version history only lists one design for the renamed design. I did not realize this had happened until several weeks later when I wanted to look back into the first design history to see how I had done something at one time.
I attempted to test this with a Design that I just threw a couple of saves into. Upon renaming, both versions were preserved so my assumption is that there is a threshold at which the renaming facility just decides, screw it.
