Operational migration

There are a few major changes in the migration from 7.x to 8.x.

The PostgreSQL version was 9.6 and is now 11.0.1
We're transitioning the filestore to Minio, but the old filestore is still in use.

There are a few services you need to migrate data from.

The file store and server properties are located in the MOLGENIS home dir. The location of this directory is configured as follows:

molgenis.home runtime property if specified in the tomcat catalina options, otherwise
molgenis.home environment variable if specified, otherwise
.molgenis dir in the user's home dir

Go to a terminal and dump your database using (as root-user):

cd /tmp/
pg_dump molgenis > molgenis.sql

Load you database using on the new server (as root-user):

Be sure you drop the database before you load the customer database.

cd /tmp/
psql molgenis < molgenis.sql

Go to a terminal and tar you files into an archive (as root-user):

cd /home/molgens/
tar -pzcvf /tmp/molgenis.tar.gz /data

Restore the filestore on the new server (as root-user):

cd /home/molgenis
mv data data_backup
tar -pxvzf molgenis.tar.gz

Go to a terminal and tar you files into an archive (as root-user):

cd /tmp/
cp /home/molgenis/molgenis-server.properties .

Restore the filestore on the new server (as root-user):

cd /tmp/
cp molgenis-server.properties /home/molgenis/ .

You need to add additional properties to make the deployment work with MOLGENIS 8.0.x

MINIO_ACCESS_KEY=molgenis
MINIO_SECRET_KEY=molgenis
