You have multiple issues:

1) Existing User Space - You really already have this with the Desktop
applications and a hardened kernel:

https://wiki.ubuntu.com/PrecisePangolin/ReleaseSchedule

2) Problems with Ubuntu 12.04 upgrade

See this post:
http://askubuntu.com/questions/126573/ethernet-connectivity-problems-after-upgrading-to-ubuntu-12-04lts

3) Need for Oracle

Please follow the instructions here to setup Oracle on 12.04
(everything should be the same): for 11gR2:

What's the difference between desktop and server?

    The first difference is in the CD contents. The "Server" CD avoids
including what Ubuntu considers desktop packages (packages like X,
Gnome or KDE), but does include server related packages (Apache2,
Bind9 and so on). Using a Desktop CD with a minimal installation and
installing, for example, apache2 from the network, one can obtain the
exact same result that can be obtained by inserting the Server CD and
installing apache2 from the CD-ROM.

    The Ubuntu Server Edition installation process is slightly
different from the Desktop Edition. Since by default Ubuntu Server
doesn't have a GUI, the process is menu driven, very similar to the
Alternate CD installation process.

    Ubuntu server installs a server-optimized kernel (tcp/ip settings
and hardened kernel) by default.

    Ubuntu Desktop will receive 3 years of support, while Ubuntu
Server will be supported for 5 years.

Is this a public facing machine?

It would probably be best to stay with your Desktop and just harden
the /etc/sysctl.conf switches, turn off all non-essential services
(bluetooth) and provide internal TRUST ip firewalling (if necessary).
