It is possible to import data from various formats (e.g.: csv, xml, etc.). It can be achieved by graphical interface (GUI) and command line (CLI).
Example command which imports data could look like this::
$ ralph importer --skipid --type file ./path/to/DataCenterAsset.csv --model_name DataCenterAsset
$ ralph importer --skipid --type zip ./path/to/exported-files.zip
To see all available importer options use:
$ ralph importer --help
Migrations from Ralph 2¶
Our generic importer / exporter allows you to easily export and import all your data from Ralph 2.
First of all export all your data from Ralph 2:
$ (ralph) ralph export_model ralph2.zip
This will export all available models to csv files and store them in ralph2.zip file in current directory.
Then import this zip file to Ralph NG:
$ (ralph-ng) ralph importer --skipid --type zip ralph2.zip
--skipid option is very important - it'll skip existing Ralph 2
IDs and assign new ones in Ralph NG.
In case of import error, fix data problems on Ralph side (for example missing field value which is required in Ralph NG), clean your NG database and repeat import again. To clear database you could run following command:
$ (ralph-ng) ralph flush && ralph migrate
