[Koha] Upgrading Koha 3.4 to Koha 3.8 ??

What is the best and easiest way to upgrade Koha 3.4 to Koha 3.8 running on Debian Squeeze? The key here is NOT to lose the data in the database tables. I am hoping that there are MySQL scripts to move data around if there are table differences between the 3.4 and 3.8. Thank you. jp -- View this message in context: http://koha.1045719.n5.nabble.com/Upgrading-Koha-3-4-to-Koha-3-8-tp5715857.h... Sent from the Koha-general mailing list archive at Nabble.com.
