convert v1 inboxes to v2


        public-inbox-convert [OPTIONS] OLD_DIR NEW_DIR


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.



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.


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

These options affect indexing.  They have no effect if “--no-index” is specified

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



The default config file, normally “~/.public-inbox/config”. See public-inbox-config(5)


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


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.
