Unless ``--inplace`` is specified, the upgrade process first
creates a backup copy of the repository, in
REPOSITORY.before-upgrade-DATETIME, using hardlinks. This takes
longer than in place upgrades, but is much safer and gives
progress information (as opposed to ``cp -al``). Once you are
satisfied with the conversion, you can safely destroy the
backup copy.
Unless ``--inplace`` is specified, the upgrade process first creates a backup
copy of the repository, in REPOSITORY.before-upgrade-DATETIME, using hardlinks.
This requires that the repository and its parent directory reside on same
filesystem so the hardlink copy can work.
This takes longer than in place upgrades, but is much safer and gives
progress information (as opposed to ``cp -al``). Once you are satisfied
with the conversion, you can safely destroy the backup copy.
WARNING: Running the upgrade in place will make the current
copy unusable with older version, with no way of going back
