In a few weeks we will be upgrading our core site to CM6.0 from 5.2 I will be getting the new call servers, session manager and system manager. In this process my network team wants to re-IP all the voice equipment. I'm assuming the night of the upgrade the CLAN, Medpro and IPSI's will need to all changed with the new IPs. Regarding the remote offices that are lsp'd off this core... does the MGC list just need to be modified for those or is something I'm missing?
