> OAK-2619 introduced the possibility to run the same upgrade repeatedly and achieve incremental upgrades. This reduces the time taken for {{CommitHook}} processing, because the diff is reduced.
> However, for incremental upgrades to be really useful, the content-copy phase needs to be fast. Currently an optimization that was proposed in OAK-2626 was lost due to the implementation of a better solution to some part of the problem.
