[Koha] Moving from Fedora to Ubuntu

[Nigel Titley]

I'm about to shift the server that currently runs Koha 2.2.3 from fedora 
Core 2 to Ubuntu Dapper Drake. I propose to use the opportunity to 
upgrade to the latest Koha (2.2.5). I'm proposing to do this as follows:

1. Dump Koha database
2. Wipe machine
3. Install Ubuntu
4. Install Koha pre-requisites
5. Install virgin Koha 2.2.5
6. Restore Koha database from (1)

Does this look reasonable? Or should I restore the original database 
between (4) and (5) and let the installation have its wicked way with it?

Help and advice very welcome.

Thanks

Nigel
