[Koha] Migrating Koha database from version 3.18 to 19.11?

[Quỳnh Vũ Đỗ]

Hello everyone

Our library has been using a Vietnamized version of Koha 3.18 since mid
2014, running on Ubuntu server 14.04 LTS. No upgrade of the system has been
made since and the server had a hardware problem (mainboard) last February.

We have a mysqldump of the Koha database (size about 1,8 GB).

So what we are trying to do is to install the latest Koha version (19.11)
on a fresh Ubuntu 16.04.6 LTS (Desktop) and then to replenish the empty
Koha tables through SQL inserts in the tables using sql exports of the
related fields from the old database. For that we have been comparing the
structure of the tables of Koha 3.18 and 19.11 with the tool provided at
http://schema.koha-community.org/

Can this way of proceeding, although tedious it might be, be successful or
not ?
If not, could someone have suggestions ?
Thanks for your attention.
Quynh
