ISPConfig 3 - Moving from Centos5.7 x86 to CentOS 6.2 x86_64

[the_matrix]

Hi to everyone,

Due to some problems on my server, I'm considering to reinstall my server that has my ISPConfig 3 installation.

So I don't have a spare machine, I will have to do a full backup and them reinstall the new server.

Current installation - CentOS 5.7 x86
Future installation - CentOS 6.2 x86_64

I'm preparing a VM with the 6.2 to test the upgrade and ALL of your input will be much appreciated.

Regarding:

- What to backup:
- How to import the backups and merging them on the new install
- Everything you might come up to.

To all my thanks.

Regards.
