Importing and exporting of templates and policy

Data file format

All template information is exported to a single file with to lists: feature_templates and device_templates. Each list contains dictionaries as pulled from the vManage API with a few additions and modifications. First, a list of attached devices and a list of input variables is added to the device template. Then instance IDs are translated into name so that the templates can be imported into another vManage.

All policy template information is exported to a single file with four lists: policy_lists, policy_definitions, central_policies, local_policies. Each list contains dictionaries as pulled from the vManage API with the instance IDs converted to names so that policies can be imported into another vManage.

Import Options

  • --check: Just check. No changes. (default=False)
  • --update: Update if exists (default=False)
  • --diff: Show diffs (default=False)

The CLI/SDK will import templates and policy idempotently and as non-destructivly as possible. It will only add templates and policies that are not there. When a template or policy does exist but is different than what is in the import file, it will not he updates unless the --update option is given.
