It was solved earlier. I had to specify the network to make it work:
iface eth0 inet static
address xx.xx.xx.xx
netmask 255.255.255.0
network xx.xx.xx.0
broadcast xx.xx.xx.255
gateway xx.xx.xx.3
dns-nameservers xx.xx.xx.xx xx.xx.xx.xx
dns-search abc.yz.net
dns-domain abc.yz.net
Also here is a short list for migration to new box:
1. LAMP,
build all accounts you need....
build all groups you need...
2. phpMyAdmin
3. get dump from old mysql: mysqldump --user=root --password=xxx --databases xx > mysql.xx.dump
4. import the dump: mysql --verbose --user=root --password=xxx < mysql.xx.dump
5. update PROXY for everything:
add to /etc/environment (need restart)
ftp_proxy=http://<myproxy>:8080
http_proxy=http://<myproxy>:8080
https_proxy=http://<myproxy>:8080
6. Install NTP and set TimeZone to Etc/UTC:
Timezone: dpkg-reconfigure tzdata
NTP: apt-get install ntp
edit /etc/ntp.conf add your servers.
add daily cron job /etc/cron.daily/ntpdate; chmod 755
stop ntp service service ntp stop
manually sync time: ntpdate <time_server>
7. Fix apt-get proxy: edit:
/etc/apt/apt.conf
8. watchout for ownership of moved over, website data
9. Enable unattended upgrades for all security patches and Apps:
/etc/apt/apt.conf.d/50unattended-upgrades
uncomment Apps update line....
10. Add a repo/PPA:
adding sun-java-6 sudo add-apt-repository ppa:sun-java-community-team/sun-java6
adding sun-java-7 http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-ubuntu-via.html
11. disable IPv6:
vi /etc/sysctl.conf (add 3 lines...)
sysctl -p
12. DHCP to fixed IP:
vi /etc/network/interfaces
13. update Repo /PPA list: (source file): /etc/apt/sources.list
All details here: https://help.ubuntu.com/community/AptGet/Howto
update available pkg list: sudo apt-get update
now upgrade the 'installed' packages: sudo apt-get upgrade
___OR___ upgrd and remove old versions: sudo apt-get dist-upgrade

ok. so I tried. I moved over all www data, personal data and matched the config (was long and tricky)
so I want to test it now, so I shut down original server at midnight and start the new one with the IP set to static (same as old server). The box comes up fine, I can ping the gateway, but I can not ping anything after it!
from old server:
eth0 Link encap:Ethernet HWaddr 00:0c:29:48:c0:18
inet addr:xxx.xx.xxx.17 Bcast:xxx.xx.xxx.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:161679 errors:0 dropped:0 overruns:0
frame:0
TX packets:41778 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:56107739 (56.1 MB) TX bytes:4452263 (4.4 MB)
Interrupt:19 Base address:0x2024
my settings on new box (which do not work, when i bring down old box and start new one.)
/etc/network$ cat interfaces.static
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address xxx.xx.xxx.17
netmask 255.255.255.0
broadcast xxx.xx.xxx.255
gateway xxx.xx.xxx.3
dns-nameservers <dns1> <dns2>
dns-search <my.dns.srch.str.here.>
dns-domain <my.dns.srch.str.here.>
xxx.xx.xxx = Class C subnet with 254 hosts.

Tyler,Nagy,
thx much for valuable input.
These are two different servers. Website is production, but can take downtime of about 1 day (weekend).
I was planning to make a tarball from old server and extract on new one, and as the last step, move the permanent IP.
But I guess MySQL has to potential to be tricky. I will try the route of dump to file and build back from that dump.
I will get back with results.
rgds.
Rajeev

I'm not aware of any differences in MySQL file storage based on
architecture. I did learn about rrdtool's architecture-dependant files the
hard way, though.
It never hurts to make and restore from mysql dumps. Just make sure you get
the "mysql" database as well, as this includes your permissions.
Regards,
Tyler
