UCCX during this process, standardized names, changed IP’s for organization purposes. The process was fairly seamless. During the migration we even went so far as to do AD integration from Call Manager and Unity Connection as we had the time, and it was
an end goal. We also went through the migration from Unity 7.0 to Unity Connection 9.1. And because we didn’t have enough to do, we even migrated our phone subnets from 6 scattered /24 subnets through our internal network into a contiguous /21 so we could
easily mask and route these subnets (including voice servers and routers) with a single statement. I also migrated and consolidated analog ports from nearly 10 year old version 1 VG248’s to 2911 routers with FXS ports on Amphenol connectors. <o:p></o:p></span></p>

from 7.x to 8.6 for call manager, implementation of Unity Connection 9.x and migration from Unity. Upgrade of Call Manager to 9.x and subnet changes for all phones. We moved from various aged MCS servers (H2 through I5) to SPEC based virtualization on HP

and Unity the actual base licensing, and skipped renewing one or the other. We went through all the nightmares and 5 TAC cases to get licensing moved from legacy mangled licensing to the new CUWL (via upgrade licensing) and ER licensing on ELM for UCM and
Connection. I’m pretty sure my AM hates me now. Did I mention that our ESW, UCSS and Licenses were all on 5 separate contracts, so we had to get those shenanigans sorted out before PUT OR ELM was even a VIABLE option?<o:p></o:p></span></p>
