To concurrently convert multiple NetWare cluster servers to OES, we strongly recommend that you use the old NetWare node IP addresses for your Linux cluster servers. You should record the NetWare node IP addresses before converting them to Linux.
If you must assign new node IP addresses to the OES nodes, we recommend that you convert only one node at a time.
If new cluster node IP addresses are required and the old server hardware is being retired, you can shut down the NetWare nodes that are to be removed, add the new OES cluster nodes, then remove the NetWare nodes’ cluster-related objects as described in Step 5 of Section 4.1, Converting NetWare Cluster Nodes to OES (Rolling Cluster Conversion).
IMPORTANT:Failure to follow these recommendations might result in NetWare server abends and OES server restarts.
