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.
