Subs don't talk to ELM. Only the Pub talks. You then have two possible setups, dedicated ELM/PLM and Colocated ELM/PLM with CUCM or Unity Connection. You also have one other scenario, rebuilding the Pub that you've mentioned. If you have the VM Resources considering all the changes you are talking about I suggest a dedicated ELM/PLM server. You can use the smallest sized CUCM OVA for this.
The following possibilities exist with moving/rebuilding: Rebuild collocated ELM/PLM and CUCM - You will have to rehost your ELM/PLM with TAC, you will also have to add the new Pub to ELM/PLM. Rebuild Dedicated Pub when having dedicated ELM/PLM. Just add the new Pub to ELM/PLM and delete. TAC not involved. Rebuild ELM/PLM Dedicated Instance - You will have to rehost your ELM/PLM with TAC, you will also have to add the existing Pub to ELM/PLM Migration of any servers -Migrating a shutdown instance of a VM using the Migrate function should cause no licensing changes as all hardware properties are kept the same. If you do a copy of the VM via VMWare that is not the case some hardware properties can change and this may cause ELM/PLM to need a rehost. A manual copy may work. I haven't tried it. I think I've addressed all of your scenarios, let me know if you need clarification. Matthew G.

They have several physical host machines configured with ESX5. My understanding of the difference with CUCM 9 is the ELM. Licenses are no longer tied to the MAC but are tied to some random characters generated by the ELM during the license file upload process. This is a lab environment so I want to be sure that I am advising them correctly on the impacts of the following actions: Assuming that both PAKs are registered to the single ELM (currently they have a Pub and Sub - each of them running inside ESX 5 on the separate physical host machines) 1 - what would be the impact if the SUB VM were physically migrated (via copying and moving ova file) to the physical machine hosting the Pub? My gut tells me no impact 2 - what would be the impact if the CUCM pub and ELM (co-existing on the Pub) were physically moved (via copying and moving ova file) to the physical machine hosting the Sub? My gut tells me no impact. 3 - what would be the impact if the Sub were decommissioned and rebuilt as a Pub in a new cluster? My gut tells me that it would take TAC involvement to rehost the license 4 - what would be the impact if the Pub were decommissioned and rebuilt as a Pub in a new lab configuration? My gut tells me that it would also take TAC involvement to rehost the license ------------------------------------------------------------------------------------ Dr. Jeffrey T.
