SDN-R Upgrade Procedure

This is still in progress

What we have to migrate?

Database:
- eventlog
- faultlog
- historicalperformance (15m/24h)
- inventory
- maintenance
- mediator-server
- required-networkelement
MD-SAL:
- mounted devices
Configuration Files:
- apigateway

So in fact that we will have the feature data-provider in SDN-R this is the best point where to start the migration process. So for El Alto we have to provide an external solution, but all later versions will have this all integrated. Therefore we have to tag the backup data with a release information so that the data can be identified and a conversion can be done if needed. So this feature may also is used as backup and restore for the same version except that (up to now) it is not planned to have a restore script for El Alto.

Database data

We will use json format so the files will be *.json or compressed json as *.json.zip.

{
    "release":"el alto",
    "created":"2019-11-19T11:43:00.0Z",
    "components":{
        "<component-name>":[{data},...],
        "<component2-name>":[{data2},...],
        "<component3-name>":[{data3},...]
    },
	"configs":{
		"<config-name>":"<config-data>",
		"<config2-name>":"<config2-data>"
	}

}
