Hi, I am planning to migrate our rasa bot from 1.10.3 to 3.x ultimately. Since, many features are deprecated and removed in 3.x, I am planning to stage migration to 2.x and eventually to 3.x. But the NLU conversion code from .md to .yaml is failing. If I run ‘rasa data convert nlu -vv -f yaml --data=./data/nlu --out=./data/nlu1’, i get the error: rasa data convert nlu: error: argument -f/–format: invalid choice: ‘yaml’ (choose from ‘json’, ‘md’) And when i run rasa data convert core -vv -f yaml --data=./data/stories --out=./data/stories1, i get the error: rasa data convert: error: invalid choice: ‘core’ (choose from ‘nlu’) What am i missing?

Hi @lokkrish Reference Video ( Ubuntu based) : MIGRATING RASA 1.x to RASA 2.0 | RASA OPEN SOURCE 2.0 - YouTube but the process will be same for Window too. Do update the Rasa and Rasa-SDK to at least 2.8.3 first and then follow: For 1.10 to 2.0 rasa data convert nlu -f yaml --data={SOURCE_DIR} --out={TARGET_DIR} rasa data convert nlg -f yaml --data={SOURCE_DIR} --out={TARGET_DIR} rasa data convert core -f yaml --data={SOURCE_DIR} --out={TARGET_DIR} Then, just update the rasa to a latest version and train the model. Please do ref this link for mode detail : Version Migration Guide Note: Other file such as config.yml you need to do manually, that will be best as my experience. I hope this will help you to solve you issue.
