How can I migrate a Splunk License Master to a brand new server without service interruption?

I need to migrate my old standalone Splunk License Master to a new server as my old License Master is being decommissioned. I need to do this without interruption to service.

My License Slaves are configured to point to a License Master FQDN. The plan is to change the DNS record of the License Master to a new IP address. What is the best way of achieving this?

A suggestion would be

"splunk stop" on old License Master
"splunk stop" on new License Master
copy over the relevant licenses from the old License Master to the new License Master
copy over etc/system/local/server.conf (which contains the pool configuration) and etc/instance.cfg from old License Master to new License Master This should ensure that the new LM conserves the same GUID
Change DNS to reflect new IP Address
Wait a few minutes and test low level connectivity from License Slaves to new License Master (ping / dig / arp -a)
"splunk start" on new LM
As a safety precaution rename /etc/instance.cfg to /etc/instance.cfg.old to ensure that if the old License Master is restarted the GUID does not clash with the new License Master
Test
