<p class="MsoNormal">I haven't upgraded anything newer than 8.5 that was on MCS so I was under the impression that the licensing MAC was used exclusively on 8.5+ as opposed to the MCS MAC, if that assumption is inaccurate, so be it, we will just need to rehost,
not the end of the world.<o:p></o:p></p>

<p class="MsoNormal">Regarding the loss of messages, this was something that I was concerned about however I thought I had read a post on the support forums (trying to find it now) where messages from the "subscriber" would be copied to the publisher after
rebuilding the publisher server from DRS? This is actually less of a concern than loosing AAs and Call Tree functionality for the duration of the migration but it's definitely a concern.<o:p></o:p></p>

<p class="MsoNormal">I understand that building a test bed is the ideal way of handling this but unfortunately finding the hardware to handle this has been a challenge and building a shadow network on the customer VM environment has not been blessed as of yet.<o:p></o:p></p>

</span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Your process will likely create a data problem, as the DRS backup will only be accurate as of when you took the backup. Since you are intending system uptime between taking
down the publisher and bring the new one online, any messages/other changes between when you take it down and bring the new one up will be lost. This is much more of a problem for Unity Connection than it is for UCM, as for UCM you mostly need an admin freeze
on any changes (plus a couple things like mobility), but any data lost is minimal and easily fixed.<br>
For Unity Connection, you will just lose any messages left or greetings changed between backup and restore.</span><o:p></o:p></p>

with the same IP/other structure, so that you can build the new 8.5 VM Servers, and then do a backup and restore (bringing down the existing system immediately after the backup with a downtime window scheduled).</span><o:p></o:p></p>
