--------------------------------------------------------------
[~baedke] you are right. When I created the patches I tried to separate
repeated upgrades from the include/exclude logic. {{NodeStateCopier}} only gets
integrated into {{RepositoryUpgrade}} in a later commit regarding OAK-2586
(Support including and excluding paths during upgrade).
I'll create a patch that includes this part. Sorry for the inconvenience.

> When upgrading from Jackrabbit 2 to Oak there are several scenarios that
> could benefit from the ability to upgrade repeatedly into one target
> repository.
> E.g. a migration process might look as follows:
> # upgrade a backup of a large repository a week before go-live
> # run the upgrade again every night (commit-hooks only handle delta)
> # run the upgrade one final time before go-live (commit-hooks only handle
> delta)
> In this scenario each upgrade would require a full traversal of the source
> repository. However, if done right, only the delta needs to be written and
> the commit-hooks also only need to process the delta.
