Upgrade Lizmap Web Client

Upgrading from Lizmap 2.x

Upgrading from Lizmap lower than 3.5 versions

You should first migrate to 3.5. See documentation of Lizmap 3.5. Then you could migrate to 3.7

Upgrading from Lizmap 3.5 or 3.6 version

Here is how to upgrade from Lizmap 3.5 or 3.6

Data backup

Backup your data and configuration files into a directory (ex: /tmp) with the lizmap/install/backup.sh script of Lizmap 3.5 or 3.6.

lizmap/install/backup.sh /tmp

If you want to backup by hand, you should backup at least these files:

var/db/jauth.db (if it exists)
var/db/logs.db (if it exists)
var/config/installer.ini.php
var/config/liveConfig.ini.php
var/config/localframework.ini.php (if it exists)
var/config/lizmapConfig.ini.php
var/config/localconfig.ini.php
var/config/profiles.ini.php

Replace Lizmap files

Get the Lizmap archive by downloading an archive on the release page.

You should then :

rename the lizmap/ directory to lizmap.bak/ for example
extract the lizmap/ directory from the archive, so it will be become the new lizmap/ directory.
execute the script lizmap/install/restore.sh /tmp or reinstall by hand the files you backup.

Note: there is not anymore a lib/ directory.

Launch the installer

You have to launch the configurator (it will upgrade some configuration files), and then the installer, which will upgrade some stuff: database tables, data etc..

sudo lizmap/install/clean_vartmp.sh
php lizmap/install/configurator.php
php lizmap/install/installer.php

Cleanup and test

You should then delete all cache and temporary files:

sudo lizmap/install/clean_vartmp.sh

Then you should call the script that sets rights on files. Parameters are the web user and the web group used by the web server to execute Lizmap. On a Debian server, it is often www-data.

sudo lizmap/install/set_rights.sh www-data www-data

Then load Lizmap into your browser, you should see your maps without errors.

If this is the case, you can delete the old directories lib/ and lizmap.bak/.

Migrating from Sqlite to Postgresql

You may have installed Lizmap with Sqlite. You should then have these files lizmap/var/db/jauth.db and lizmap/var/db/logs.db, where some data like users, permissions and logs are stored. And you should have this configuration into lizmap/var/config/profiles.ini.php:

[jdb:jauth]
driver=sqlite3
database="var:db/jauth.db"

[jdb:lizlog]
driver=sqlite3
database="var:db/logs.db"

It you have a such configuration, you can migrate data to a Postgresql database.

First, create a Postgresql database, and then change the configuration into lizmap/var/config/profiles.ini.php, by setting access parameters to the Postgresql database. It is recommended to create a schema into the database, for example lizmap , if it contains already some tables.

For example :

[jdb:jauth]
driver=pgsql
host=localhost
port=5432
database="your_database"
user=my_login
password=my_password
search_path=lizmap,public

[jdb:lizlog]
driver=pgsql
host=localhost
port=5432
database="your_database"
user=my_login
password=my_password
search_path=lizmap,public

See the chapter about installation to know more about these parameters.

Then you can launch these scripts which will migrate the data.

php lizmap/console.php database:migrateusers
php lizmap/console.php database:migratelog

If there are no errors, you can then go onto lizmap with your browser, and check that you can authenticate yourself. You should see also the list of users into the administration panel. If this is the case, you can backup files jauth.db and logs.db and you can delete them.

If something goes wrong and you cannot fix the issue, revert the database access into lizmap/var/config/profiles.ini.php as before, like this :

[jdb:jauth]
driver=sqlite3
database="var:db/jauth.db"

[jdb:lizlog]
driver=sqlite3
database="var:db/logs.db"

And Lizmap should work well, but still with Sqlite.
