<span class=content1><font color=black face=Arial>Hopefully one of you guys
have been through this and can recommend the most painless way forward.... </font></span><br>
<br>
<span class=content1><font color=black face=Arial>We have a customer who
currently has an old 3.3.3 CCM Cluster with about 2000 phones hanging of it. </font></span><br>
<br>
<span class=content1><font color=black face=Arial>They need to go to CCM 4.x
and want to prove the environment / product first by staging the new CCM 4 and
then gradually moving users from the old cluster to the new cluster. The
downside of this is that it is not a straightforward upgrade / replacement as
the two clusters will live side by side for a while. </font></span><br>
<br>
<span class=content1><font color=black face=Arial>I have no problem with this
apart from the sheer numbers involved. My initial thought was to use the BAT
tool to import all data from the production cluster to the CCM4 cluster - but
that still leaves me loads of stuff to cross-pollinate i.e. Route patterns,
partitions etc...etc... </font></span><br>
<br>
<span class=content1><font color=black face=Arial>My second thought is to build
the CCM4 cluster from the Upgrade 'Replace Server' option whilst building -but
that forces me to use the old CCM3's machine name etc so the two clusters
cannot live side by side....unless there is a way to build the CCM cluster by
the 'Upgrade Replace Server' option and then rename the machine name and change
IP addresses etc... </font></span><br>
<br>
<span class=content1><font color=black face=Arial>BTW I know everyone says that
you cannot change machine names because of SQL (but has anyone actually tried
this?) - there are snippets of info available on the web detailing how to
change SQL machine names. </font></span><br>
<br>
<span class=content1><font color=black face=Arial>Any advice gratefully
received. </font></span><br>
