A full conversion of the modules on Nuvla to a CIMI representation has been performed on a test SlipStream deployment. The full conversion took a bit under 3 hours (167 minutes) with the script running on a laptop separate from Nuvla and the test machine.
The known limitations of the migration script are:
- ACLs are not migrated:
- Decision on how to map the build, run, other rights in the ACLs.
- Decision on what to do with ACL inheritance.
- Treatment of connector-specific options.
- Creation/updated dates are currently reset to current date. Determine how to preserve these.
As there are now "project" resources, the module resource implementation needs to check/ensure consistency in the module hierarchy: not allow addition of modules without a parent, check ACL of enclosing project, no duplication of paths, etc.
The errors that arise in the conversions are summarized below:
- References to non-existent components.
- Components without a parent component/image reference.
- Module changed type image/component in its history.
- Invalid parameter/node names.
- Other invalid parameters: ram, author, os.
- Character encoding issues.
The character encoding problems need to be fixed in the migration script. The others problems require us to decide what to do with invalid module specifications: try to correct errors, ignore modules, etc.
