Migration guide

This documentation describes migration process to a recent Sugarizer Server version.

Migrate to 1.5.0

Two new collections need to be added to the [collections] section of your .ini file:

assignments = assignments
activities = activities

Sugarizer Server version 1.5.0 require MongoDB 3.2+. Recent versions of MongoDB don't support old database file format so we recommend to dump your current database before upgrading to avoid losing data.

Depending from the way you're running Sugarizer Server, follow the migration guide below.

See MongoDB documentation for more information.

Running Sugarizer Server on your computer

If Sugarizer Server and MongoDB run from your computer.

First stop Sugarizer Server, then launch dump command.

mongodump --db=sugarizer

A dump/sugarizer directory has been created on the db directory.

Now stop MongoDB and upgrade it to a recent version. Then launch the new MongoDB engine.

Finally, launch the restore command.

mongorestore --db=sugarizer dump/sugarizer

Running Sugarizer Server using Docker

First identify the id for the MongoDB container by running.

docker ps

The id is the one on the line named sugarizer-server_mongodb.

Now attach a bash shell on the running MongoDB instance by running:

docker exec -it <IdOfDockerForMongoDB> /bin/bash

Then launch the dump command. :

cd /data/db 
mongodump --db=sugarizer

You could exit from the bash shell. A new directory dump has been created in sugarizer-server/docker/db.

You must now delete the container and the old MongoDB image. Type following commands:

docker rm <IdOfDockerForMongoDB>
docker rmi sugarizer-server_mongodb:latest

You could now upgrade Sugarizer Server, probably just by doing a git pull.

Once Sugarizer Server is upgraded, regenerate the docker file by a call to:

sh generate-docker-compose.sh

Then run new containers:

docker-compose up -d

It could take some time and a message telling than mongodb is building should appears.

Follow the same process than before to attach a bash shell on the new running Mongodb instance:

docker ps
docker exec -it <IdOfDockerForNewMongoDB> /bin/bash

Finally launch the restore command:

cd /data/db 
mongorestore --db=sugarizer dump/sugarizer
