Hello @xdobetter,

I don't think that such a tool exists, and we haven't really had a need for it because the formats for 0.5, 0.6 and 3.0 are very similar, so fixes can typically be applied by hand.
Moreover, most incompatibilities will be due to plugins that haven't been implemented in Mitsuba 3, so an automatic conversion wouldn't be able to fix that.

I think the easiest way is to try loading the scene in Mitsuba 3, checking the error message, applying the fixes, and repeating until the scene loads.
It's a bit of manual work, but in any case you would have to decide for yourself what to replace the missing plugins with.

I hope this helps!
