</div>Ugh. Tough luck. My upgrade from 4.1(3) was to 5.0. The last upgrade I<br>
had to do of a 4.x version turned out to be a manual takeover of all<br>
configuration (luckily, it was a small setup of less than 100 phones<br>
and a welcome break with old stuff and opportunity to clean up historic<br>
cuft). The reason for doing it manually was that I didn't trust DMA<br>
enough to install it on the SPOF fragile old non-clustered 4.x box<br>
(remember, DMA actually drops an entire RDBMS on the poor machine),<br>
and we couldn't get hold of *ANY* installation media for the OS in<br>
question. Original media was MIA, Cisco could provide CCM install media<br>
to no avail, but Win2k3 appliance OS media - no chance. So I tried<br>
for a while to prep a W2k3 install to accept CCM, but gave up on that<br>
finally - burned too much time. Time better used for a fresh start.<br>
<br>
What you can do depends entirely on software and hardware you have<br>
available or can get hold of.<br>

</div>Uhm. So you want to go virtualized. That makes things a little harder, given<br>
Mike's advice to not run 7.x in a VM even as an intermediate step. The problem<br>
being, you cannot go from 4.x to 8.x directly as the DMA was phased out with<br>
7.x the last supported target. And you need DMA.<br>

<br>
</div>I would try to proceed as such:<br>
<br>
1) Clone the existing 4.1 onto another machine. That could be another<br>
DL380G3. If you can live with some downtime, it can be the one you<br>
already have. If you must minimize downtime, and want to risk a DMA<br>
on the original pub, there is no need to clone.<br>
2) Install DMA (on the cloned or original 4.1) and produce a DMA dump<br>
of the DB. Be aware that DMA is a full Informix install, a bunch<br>
of scripts reading the old DB and merging it into new structures in<br>
Informix, and finally a full dump of the Informix tables into an<br>
external file.<br>
3) On some hardware that is feasible, install 7.1(3) or something that<br>
is similarly reliable, works on your hardware and you can get hold of<br>
the media easily for (anything 6.x or 7.x should do). Import the DMA<br>
to this machine.<br>
4) Upgrade this machine to 8.6 and export using DRS (the standard backup<br>
system that replaced BARS). The upgrade could be direct or bridged,<br>
depending on hardware. It makes no difference, as all you want to<br>
produce is a DRS backup.<br>
5) Do a completely new installation of 8.6 in a VM on your target platform,<br>
based on machine templates provided by Cisco, then restore from the DRS<br>
backup. If it looks plausible, deal with licensing. Regarding licensing,<br>
it *MAY* be necessary to deal with that already on the DMA import step<br>
to 7.x. There was no device licensing on 4.x, so Cisco would just sign<br>
you a license file produced in the DMA step. As licensing has changed<br>
again in 8.6, it may be too late to start that process here. I simply<br>
don't know, I don't even know if the process for licensing all your<br>
phones on DMA upgrade is still available, but I assume it is.<br>
<br>
That's the raw sketchy outline of a plan I would start with. Details like<br>
to fill in themselves in the process, sometimes vigorously rearchitecting<br>
your nice theory ;)<br>
