Migrating linux server

There is a small, tiny server running for small community.
It's running 24 hours, 7 days in my closet. ;-)
The server is operated in ubuntu linux.
Main purposes of this are sharing files through ftp, running small board, downloading from torrent, remote access from the office through secret ssh port, sharing files through samba.
Yes, It is doing a lot of work as small home server.
but hardwares running linux are not so powerful.
celeron 1GHz, 512 Mb memory, and harddisks of 10Gb, 80 Gb, and 80 Gb.
(VIA 694 chipset)

One of my collegue gave me a old computer.
It has Celeron 2.6 GHz (!), 256 Mb memory, and 40 Gb harddisk.
(Intel i845G chipset)

So I decide to migrate my old server to new -actually it is not a new one - machine.

This is my personal recording of migration process.

1. Intall Ubuntu linux from 8.10 CD.
2. Upgrade ubuntu linux from 8.10 to 9.04 through dist-upgrade.
3. Configure APM (Apache2, PHP5, MySQL5 )
4. Install additional softwares
(proftpd, openssh, telnetd, webalizer, phpmyadmin, mc, squid)
5.
