SYNOPSIS
git annex upgrade
DESCRIPTION
Upgrades the repository to current layout.Each git-annex repository has an annex.version in its git configuration, that indicates the repository version. If git-annex changes to a new layout, you must upgrade the repository before git-annex can be used in it.
To see version information, run git annex version.
Currently, git-annex supports upgrades all the way back to version 0, which was only used by its author. It's expected that git-annex will always support upgrading from all past repository versions -- this is necessary to allow archives to be taken offline for years and later used.
