Upgrade from 71 to 2015

[fbernigaud_]

it is about upgrade from 7.1 to 2015. In the doc "How to upgrade" I do not see a step "restore". At which step is reloaded data from backup ? Is their any change in the data model from 7.1 to 2015 and do we need a migration script ?

You're talking about ADMINDOC/Upgrading the Nuxeo Platform and ADMINDOC/Upgrade from 6.0 to 7.10 and maybe also ADMINDOC/Backup and Restore.

Restoring

1. Restore the database and data filesystem you had previously backed up.
2. Configure Nuxeo to use this database and data directory.
3. Start Nuxeo.

What is your question regarding the above sentence?

Is their any change in the data model from 7.1 to 2015 and do we need a migration script ?

Yes, there are some important changes requiring a migration script for some specific configurations. You will have to look into that page and the upgrade notes if your environment matches some of the cases for which a data migration is needed.
