Migrating Splunk Enterprise instances to new servers, what steps do I need to follow with a deployment server?

Contributor

I currently have a Splunk environment that consists of:
1 License Manager/Deployment Server
1 Search Head
2 Indexers
1 Universal Forwarder

For reasons beyond my control the, VMs that currently host my Search Head and Indexers are being taken away. I need to create new VMs and move the search heads and indexers to the new locations. All the servers are Linux 64 bit, same OS, and all Splunk instances are 6.3.1

From the documentation, the recommended steps are to:
1) stop the instance you want to migrate;
2) copy contents of $SPLUNK_HOME to the new server;
3) install Splunk over the old stuff;
4) start Splunk on new server.

I can't find anywhere that talks about migrating to a new server when deployment server is involved. I'm thinking I need to add the following steps:
3a) On deployment server, update the deployment-apps as required to reflect new hostnames or ips
----Do I need to update any deployment server configuration (like which servers belong to which class), or can I do that via the forward management UI when the servers connect? ----
3b) Do a reload-server

I feel like I'm missing something...does this list look complete??

Thanks!

I guess following configuration updates are needed

  1. You would've to update serverclass.conf on deployment server to reflect new deployment-client IP/hostname.
  2. You would've to update deploymentclient.conf on deployment-clients to reflect new deployment server IP/hostname.
  3. You would've to update the reference of License Server in server.conf on all instances (SH and Indexers and Forwarders)
  4. You would've to update distsearch.conf on Search Head to update the new search peers (Indexer) IP/hostname
  5. You would've to update outputs.conf of forwarder with new Indexer IP/hostname

I guess, updates from point 3 to 5 are being handled by deployment apps.
