Hi Neha,


Generally best practice is to add the new node before removing the old one.=
 This is especially important if the cluster=E2=80=99s resources (such as =
available disk space) are low. Also, adding a node usually asserts that the=
 node is functioning correctly (check logs) before decommisioning the old =
node. See [1].
