noblogsmv
=========

A script that drives the transition between two different backend maps
for the Noblogs databases. The process is meant to be driven by a
single script (the "driver"), running on a single host. This script
will save its state locally, so that it is easily restartable in case
it is interrupted.


Usage
-----

When performing a backend migration, you need first to have the
two blog->backend maps ("old" and "new") in JSON format. You can
get them by running the 'noblogs' admin command with suitable
arguments.

Then, create a new, empty directory on the driver host::

    $ mkdir /var/tmp/migration-01
    $ cd /var/tmp/migration-01

And run the driver script::

    $ sudo screen noblogsmv-driver \
        --old-map=old.json \
        --new-map=new.json

The web console will be available on http://localhost:3030/.
