How to Best rsync 2 boxes (Same OS, Different Arch)

Hello Fellows,
Happy Day, I hope..

Dear all, I have this thing in hand..
I few months ago had a VPS which I spent days setting up what I need into it..
And I finally got it to work like a charm.. exactly like I need.

Alright, couple days ago.. I needed to take another one, and I went through that..

Now, I have 2 VPS.. Like below:

The Old VPS:

Code:

[root@mail /]# cat /etc/redhat-release
CentOS release 5.4 (Final)
[root@mail /]# uname -a
Linux mail.Old-Domain.com 2.6.24-24-xen #1 SMP Tue Aug 18 18:15:39 UTC 2009 x86_64 x86_64 x86_64 GNU/Linux

The New VPS:

Code:

[root@mail /]# cat /etc/redhat-release
CentOS release 5.4 (Final)
[root@mail /]# uname -a
Linux mail.New-Domain.com 2.6.18-128.2.1.el5.028stab064.7 #1 SMP Wed Aug 26 15:47:17 MSD 2009 i686 i686 i386 GNU/Linux

I used this command below to rsync the /home (Web Root), and was amazing..

Code:

rsync -avhe ssh /home/websites root@DIST.SERVER.IP:/home

What I'm wondering about now, is which are the directories I need to rsync so I get the exact same setup at the other side?

That's it in short.. and again.. hope you a sunny charm-full day.

Apparently your 'old' system has a newer kernel (2.6.24) than your 'new' system (2.6.18) ....

I agree..
in fact in VPSes I noticed that you can't upgrade the kernel..
I has to be done via the VPS provider.

Any thoughts about migrating my setting and application to the new one?

Thanks..

I know how to do this sort of thing on Debian based machines, using the installed package list and database of package configuration options, but clearly it would be different on a Red Hat based distro like CentOS. As such you may do better asking on Red Hat or Fedora forums.

However it also depends on how much of your configuration was done within the framework of the package manager and how much was done by hand.

Regarding what directories you need to sync, depends on what you've installed and configured.
