[Koha] Upgrade from Koha 3.08.07

[Nigel Titley]

I'm running an extremely antique version of Koha 3.08.07 on Debian Squeeze.

For various reasons (mainly the fact that the system is enormously
stable) nothing has been upgraded for a long while but it's getting to
the point where I need to upgrade it. I'm planning at the same time to
move Koha off onto a new system running the latest Ubuntu LTS. I'm happy
with installing a brand-new Koha but how do I go about transferring the
data. I've found instructions for shifting the database but will the
database schema upgrade work with that huge a jump? It's not a huge
library, just a couple of thousand books.

Thanks for any help that anyone can offer.
