@on_wisdom_181819 When using OpsCenter Lifecycle Manager, a binary program called meld is copied to target nodes at the beginning of each LCM job. This program is executed by LCM on the nodes to perform tasks such as install, configure and manage DataStax Enterprise and the DataStax agents.

If you are configuring sudo access for the server login user, the only privilege it requires is to run the command sudo meld from the user's home directory on each node.

For more details, see Running jobs in Lifecycle Manager. Cheers!
