noblogsmv is 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.
To install from source in a Python virtualenv:
$ virtualenv venv $ ./venv/bin/pip install git+https://git.autistici.org/ai/noblogsmv.git#egg=noblogsmv
This will install all the required dependencies and it will put the
driver script in
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
