NAME
    public-inbox-convert - convert v1 inboxes to v2

SYNOPSIS
            public-inbox-convert [OPTIONS] OLD_DIR NEW_DIR

DESCRIPTION
    public-inbox-convert copies the contents of an old "v1" inbox into a new
    "v2" inbox. It makes no changes to the old inbox and users are expected
    to update the "inboxdir" path in public-inbox-config(5) to point to the
    path of NEW_DIR once they are satisfied with the conversion.

OPTIONS
    --no-index
        Disables Xapian and overview DB indexing on the new inbox. By
        default, public-inbox-convert creates a new index in the v2 inbox
        and indexes all existing messages, a lengthy operation for large
        inboxes.

    -j JOBS, --jobs=JOBS
        Control the number of indexing jobs and Xapian shards of the v2
        inbox. By default, this is the detected CPU count but capped at 4
        due to various bottlenecks. The number of Xapian shards will be 1
        less than the JOBS value, since there is a single process which
        distributes work to the Xapian shards.

    -L LEVEL, --index-level=LEVEL
    -c, --compact
    -v, --verbose
    --no-fsync
    --sequential-shard
    --batch-size=BYTES
    --max-size=BYTES
        These options affect indexing. They have no effect if "--no-index"
        is specified

        See public-inbox-index(1) for a description of these options.

ENVIRONMENT
    PI_CONFIG
            The default config file, normally "~/.public-inbox/config". See
            public-inbox-config(5)

UPGRADING
    Editing "~/.public-inbox/config" (or whatever "PI_CONFIG" is set to)
    will be required to start using the new directory.

BUGS
    Writes from public-inbox-mda(1) or git-fetch(1) to the v1 inbox which
    occur after the start of the conversion will not be picked up in the v2
    inbox.

    Users of public-inbox-watch(1) do not have to worry about this. They
    only need to update the config file to point to the v2 inbox, send
    "SIGHUP" public-inbox-watch process to reload the config file, and then
    "SIGUSR1" to rescan existing Maildirs.
