Steps to reproduce,
Create older version of CDAP (6.2 or 6.1)
Deploy pipeline with plugins that has version ranges.
Upgrade to CDAP to 6.3
Post upgrade clone the pipeline
After cloning, deploy the pipeline
Post deploy the backend throws an error that it is not able to find the plugin.
The underlying cause is, UI is not upgrading parent artifact version (cdap-dev-pipeline). This causes deploy/preview to fail.
The workaround to this issue is to save to drafts or export and import the pipeline.
