Migration Guide

From 3.x to 3.1

ModernMT models from 3.x can be ported to version 3.1. In order to do that we let ModernMT re-create both Translation Memory and Context Analyzer from scratch reading the update history stored in the Kafka queue.

Once you have updated the software, get rid of the old models (assuming default engine):

# Ensure ModernMT is stopped
./mmt stop

# Get rid of old models
pushd engines/default/models
mv context context.bak
mv decoder/memory decoder/memory.bak
popd

Now simply restart ModernMT to re-create the models from the queue:

./mmt start
