User documentation: SDN-R Upgrade Procedure

Migration Concept El Alto → Frankfurt

...

• Migration is like re-installing a backup and fills data into database. 
• User is responsible to have SDNC cluster in approppriate status to receive backup/migration data

...

• Response: 200 OK If job is accepted
• Response: 4xx if not acceped (e.g. already running or file not found or invalid)

...

This will be a CommandLineTool for:

• (re)initialize/upgrade SDN-R DB
• backup and restore SDN-R DB data
• create unit test init-file

Its sources are located in the data-provider subproject of ccsdk/features  sdnr/wt projects but it won't be deployed as a bundle for opendaylight, so that it is possible to run it independently from any sdnc.

Structure:

In Elasticsearch(ES) there are no database and datatables. Instead there are indices and doctypes. Since version 5.0 of ES only one doctype per index is allowed, so that we can say our index equals the table in a normal relational database like mariadb.
