The customer wants to migrate their current Splunk Index cluster to new hardware to improve indexing and search performance. What is the correct process and procedure for this task?
A.
1. Install new indexers. 2. Configure indexers into the cluster as peers; ensure they receive the same configuration via the deployment server. 3. Decommission old peers one at a time. 4. Remove old peers from the CM's list. 5. Update forwarders to forward to the new peers.
B.
1. Install new indexers. 2. Configure indexers into the cluster as peers; ensure they receive the cluster bundle and the same configuration as original peers. 3. Decommission old peers one at a time. 4. Remove old peers from the CM's list. 5. Update forwarders to forward to the new peers.
C.
1. Install new indexers. 2. Configure indexers into the cluster as peers; ensure they receive the same configuration via the deployment server. 3. Update forwarders to forward to the new peers. 4. Decommission old peers on at a time. 5. Restart the cluster master (CM).

I also go with D
I think the Forwarders should be updated befor decomissioning the old peers so that they do not try to send to already decomissioned systems...
C and A are wrong as the DS is not used for Index Cluster management or IDX apps
B could also be be used if want to age out data on the existing peers or ensure that the new peers are receiving data before taking the existing peers offline
