Checking progress manually
You can check site.pp in the Puppet repo . See how many hosts are using the old elasticsearch::cirrus role vs. the new cirrus::opensearch role
If you have cumin access, you can also run the following commands: sudo cumin O:elasticsearch::cirrus for the old role, sudo cumin O:cirrus::opensearch for the new role
