Currently, I'm running BM 3.6 on NW5. We use Server to Server VPN,
Client
to Server VPN, firewall and proxy services. I'm trying to figure out
the
best way to upgrade to NW6 and BM 3.7. I would like to use the same
filter
exceptions and the same IP addresses(plus I have several secondary
public IP
addresses).

Should I:

Upgrade BM and then NW
Upgrade NW and then BM
Create a NW box with BM and replace it altogether

Also, should I do it in stages, or all at once?
Should I consider performing a migration?

I'm very concerned about performing this upgrade. BM 3.6 took quite a
while
to get right(thanks Craig, your website is invaluable) and I want to
avoid
as much downtime as possible.

Any advice would be appreciated.

Thanks!!!
