I really have to wonder. The transition from feudalism to capitalism was largely centered around various "islands of capitalism" where capitalist and protocapitalist relations took root while other areas sustained their feudal relations. Eventually, the discrepancy between the functioning of the state and the economic realities of the country became so wide that the whole facade collapsed.
Another, as of yet unexplored, instance of this occurring was with Roman production: The freeholds of the Republican and early Imperial eras of Roman history gradually declined in favor of the more productive villa, which eventually evolved into the manor. The villa finds it origins in olive cultivation in Spain and in France, small islands among largely different production relations. Over time, the self-sufficiency of villas eroded Roman authority in the various areas ruled by the Western Roman Empire and eventually, it simply dissolved.
Indeed, it seems to me that the economic base begins changing long before the political establishment catches up, and that it is this discrepancy that generates crises in the first place.
It is perhaps tempting to bring up the development of Prussia, Austria, Japan etc. as examples of "peaceful" mode of production change, but was it really all that peaceful? Most countries that progressed from feudalism to capitalism in this era either A. Were affected by revolutions of their own, as was the case with Prussia in 1848 and with Japan during the Boshin War, B. Were imperialised by capitalist countries and had capitalism forced upon them, or C. They did not advance significantly beyond feudalism in the era, as could be seen in Russia and Austria.
Again, the same can be said for the transition for freeholds and tribal production to feudalism. The Carolingian Empire brought feudalism all the way to the Elbe at swordpoint, the Kingdom of Asturias exported it to the Muslim Kingdoms in Southern Spain, the Byzantine Empire adopted feudalism in the midst of it's hundreds of civil wars and the general erosion of it's authority, and many more examples I haven't touched upon.
What makes this sort of transition impossible in the context of capitalism to socialism, and how are we able to overcome that? Class consciousness and revolutionary spirit did not spontaneously arise in the French, it was cultivated by material advancements between the 14th century to the 18th century. Why would the proletariat suddenly, and without basis, gain class consciousness and revolutionary spirit?
And if such a transition is possible, what can we do to foment it? How do we create these islands?
