Nicolay, This is the upgrade procedure that I recently used. - Install Ubuntu server 16.04. I ran up a new host on my ESXi server. - I followed the install procedure from the wiki (https://wiki.koha-community.org/wiki/Koha_on_ubuntu_-_packages). I used Mariadb - I replaced the "library" (koha instance) in the procedure with the name from the old server. - I run the web installer. - Then I drop the database in the new server. - Backup the database from the old server. - Import the backup into the new database. Examples$ mysql -u root -pNow drop database:mysql> DROP DATABASE koha_lcsdnvlib;Now create database again:mysql> CREATE DATABASE koha_lcsdnvlib;Exit and close the session:mysql> quitgunzip *.gzLoad file mysql  -u root -p koha_lcsdnvlib < /var/lib/automysqlbackup/daily/koha_lcsdnvlib/koha_lcsdnvlib_2014-06-19_06h30m.Thursday.sql rebuild zebrasudo koha-rebuild-zebra -f -v -v library restart server  Joseph Lamb On Tuesday, June 27, 2017 7:08 AM, Деловой Библиотекарь <mgdb@live.ru> wrote: Hi, Tim

It would be helpful to know if you upgraded using package or tarball.

[Николай Ластовка] I upgraded start command "do-upgrade-release", I have no mind is it package or tarball, sorry!

It also helps to know what *nix distro you are using (Centos, Ubuntu, etc)

[Николай Ластовка] ok! We used Ubuntu Server 11.10, now we have 12.04

It looks like you may need to install a package?

You can usually see if the package is installed by running: locate Cache/Memcached.pm

If you have it, it should show up something like: /usr/share/perl5/Cache/Memcached.pm

In Ubuntu, you may need to install libcache-memcached-perl apt-get install libcache-memcached-perl

If you are using a redhat derivative, you may need to yum install perl-Cache- Memcached

[Николай Ластовка] we fixed problems, installed packages as you write. And in general Koha work. Now I have some questions: - how start SIP server (our RFID selfbook don't work because not connected to database); - need I upgrade to next release of Ubuntu (up to 12.10); - best version of Koha we can update (we have ver. 3.06.03.00) and what we must to control (we have some files in Russian lang); Thanks fo answer, Good luck!
