> Repo migration from old segment to oak segment tar requires heap memory
> proportional to the repository size, which does not scale well for
> large-scale repositories. Also, some structures (e.g. lots of direct
> children) have a big impact on the memory footprint.
> For some repositories, the sidegrade requires as much as 40GB heap to perform
> the migration, which might not be an option for most of the customers.
