This may be a dumb question, but in looking at what the server migration
tool does to move from a 32 bit machine to a 64 bit, I was wondering if I
needed to use the tool.

The docs say, the migration tool copies, the conf files and content to a new
serve then changes the name of the server and changes the networking.

Can I:

manually copy/backup the conf folder
Manually copy/back up the cert
Manually back up Databse folder
Shut down that ZCM server

Start up my new server, with same name, IP address and ZCM version number
and then

Copy all my backed up files into the appropriate folders?

I would have thought that if my 64 bit server has the same name and IP
address and same folder structure as my original server then it should work

OR does the migration tool do something else?
