Stop the server.
$ covalent stop Covalent server has stopped.
Install the new version of Covalent using Pip.
$ pip install covalent==0.202.0 --upgrade $ pip show covalent | grep Version Version: 0.202.0
Migrate the database.

Use the data migration tool to migrate any workflows you want to port to the new version of Covalent.
For example, for a workflow with dispatch ID
$ covalent migrate-legacy-result-object ./results/e0ba03a2-fdc0-474e-9997-7fa8e82932c5/result.pkl Processing result object for dispatch e0ba03a2-fdc0-474e-9997-7fa8e82932c5 Processing node 0 Processing node 1 Processing node 2 Processing node 3 Processed transport graph Processed lattice
Navigate to the UI (http://localhost:48008) to view your workflows.
