upgrade ubuntu server

hello i am currently running
The Perfect Server - Ubuntu 9.10 ISPConfig 3

and i was looking to upgrade to
The Perfect Server - Ubuntu 10.10 ISPConfig 3

i have a few questions


first what would be the best way to upgrade to 10.10

should i load a new box with 10.10 have everything running and transfer the sites over to the new box go live and then upgrade the older box? what is the best way to do this?



second how could i have both servers running under one outgoing ip

server 1 192.168.1.111
server 2 192.168.1.112
both pointing to port 80

or would i run

server 1 192.168.1.111 to port 80 and
server 2 192.168.1.112 and point it to 192.168.1.111


third question question

could i use the newer install 10.10 to run the older 9.10.. another words could i just log into the 10.10 box server2 and make changes on server 1

I think you should use the Update Manager:

http://www.howtoforge.com/how-to-up...-to-10.10-maverick-meerkat-desktop-and-server
Maybe make a backup of the system before you do this.

You can make your router forward a port to just one server, so you cannot access the second server directly. But you could set up a reverse proxy. This link should give you the idea: http://www.howtoforge.com/apache_reverse_proxy_ispconfig

Sorry, but I don't understand?

 

thanks falko thats great news for me lol last question does not matter


now the question i have is how do i make a backup of the server? and is there a way to make daily backups of the server and is there a how to for it?

You can find some tutorials in the "Backup" category. What you want to use depends on if you want to do file- or image-based backups.

ok i guess the best thing to do is make a complete backup of the server manually

and then make daily updates for the var/www area automatically

i have 2 disks on the server

SATA device A partitions

Code:

1 	Linux 		94.13 MB 	1 	12 	/boot
2 	Extended 	232.79 GB 	13 	30401 	
5 	Linux swap 	957 MB 	13 	134 	Virtual memory
6 	Linux 		231.86 GB 	135 	30401 	/

SATA device B Partitions

Code:

1 	Linux 		232.88 GB 	1 	30401 	

i would like to use SATA device B for the backups. what would you recommend i use to complete these routines.

thank you for all you help falko.

I guess I'd try dd to create a copy of your first hard drive on the second one.

 

I am sorry falko I think my question was not clear.


I wanted to know what program I should use to make a copy of
sata a to sata b

and what program I should use to run daily updates of the var/www directory


can I use the same program or different ones?


I use a program called acronis to do these backups on my windows machine but they only support ubuntu 9.04 or older.

I hope I was a bit clearer this time.
thanks once again
