.SH NAME
git\-annex upgrade \- upgrade repository layout
.PP
.SH SYNOPSIS
git annex upgrade
.PP
.SH DESCRIPTION
Upgrades the repository to current layout.
.PP
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.
.PP
To see version information, run \fBgit annex version\fP. 
.PP
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.
