Although I have long been a fan of Mozbackup, it's no longer under
development, and the developer's web page indicates that there's an
increasing number of things in the Mozilla architecture (even before
Quantum) that the last version doesn't account for.
Seamonkey (and for that matter, Thunderbird) may still be close enough
to the expectations that Mozbackup has, that you might be able to use it
to move to a new machine, but you would need to be prepared for the
possibility of problems in the profile on the new machine.
It is fairly simple to copy a profile, as noted above. Re-ambiguating,
the location, the location that will work on both machines is
%APPDATA%\Mozilla\Seamonkey, and if you copy the entirety of the
Seamonkey folder, that will grab all your profiles (if you have more
than one), and put them into folders with identical names. And you
should do that before launching Seamonkey for the first time (and
bypassing the initial start of the profile manager).
This approach will get *all* your Seamonkey data, including prefs,
bookmarks, mail stores, address books, server configs, and extensions.
About the only thing that Mozbackup accomplishes is that that one gives
you the ability for more granularity of what you back up or restore, and
it saves you from having to root around in your file system, of finding
the right folder(s) amid hidden folders, the specific names used in
system user IDs, or environment variables.
Although you're not asking the question, if you're wanting to move to
Seamonkey on a Linux platform, you could copy all your data to
$HOME/.mozilla/seamonkey -- it's that portable. And it's also possible
to do the same thing with Mac, although I'm not fluent enough with Mac
that I remember the exact location and environment variable used.
