well, you did some weird things first, so it's hard to say whether you 
broke something trying the various unsupported things before you got here.
i've been running a dual server config since the 90s, with hardware that's 
been running, well, since the 90s (i guess the pc is newer but the 
filesystem has moved with the hostname over time)

um. if you're not careful you'll screw yourself again. if you do that make 
sure you
1) migrate the database files
2) properly edit all CellServDBs (client and server)

if you are turning off the old server, addsite won't help. if you intend 
to have both up, well, you can only have one master copy, so you can 
create on exactly one host, and then addsite on both (and release)
