I have a BM3.6 server and am changing the hardware. How can I backup all BM
configuration information (Filters, Setup, proxy settings, access rules,
etc) and restore it on a different server. Does anybody have a program to
backup and restore the full BN configuration?

It seems the best to set two BM servers in the tree at a second public
address, copy/restore for the old server configuration. Then test, test,
test. When the new server is ready, change the private address to the old
server private address (and change the old server address to a unused by
users for gateway or proxy. Then also chage the public adress to the old
server public address ( again chage the old server public address to a
unused public).
