Hello [php 5.6.35, Mysql 5.7.21, Apache 2.4.33]
I tried today to upgrade my ojs 2.4.8.2 installation to ojs 3.1.1-2. using the classic method (Replacing the current OJS directory with the new OJS directory and then filling the configuration file config.inc.php with the correct parameters)
I enabled the display of errors. This is an example of errors I got :
Strict standards: Declaration of AnnouncementFeedPlugin::register() should be compatible with LazyLoadPlugin::register($category, $path, $mainContextId = NULL) in E:\wamp64\www\revue\plugins\generic\announcementFeed\AnnouncementFeedPlugin.inc.php on line 148

Did you use the ojs-3.1.1-2 tar package?
You should not replace the old ojs folder with the new, but use a new folder for 3.1.1-2 or remove the old and take the clean 3.1.1-2 code. It seems like you still have some old code there – Lucene plugin does not exist in 3.1.1-2 any more.
Thus it would be best to:
backup everything from 2.4.8.2: files folder, public folder, config.inc.php, DB dump!!!
unpack the ojs-3.1.1-2 tar package in a new folder
copy the public folder to the new ojs folder, eventually copy the 2.4.8 files folder to the right location, create a new, clean DB and apply the 2.4.8 dump on it, adapt the new config.inc.php.
start the upgrade via CLI, using the command “php tools/upgrade.php upgrade”.
Every time you start a new upgrade attempt, you would need to do all the steps 3. and 4. again – an upgrade attempt moves the files and changes the DB, so that they could be wrong when starting a new upgrade – they always need to be as in the original 2.4.8 installation.

First I want to thank you for the quick answer.
Yes I used the tar ojs-3.1.1-2 and replaced the current ojs 2.4.8 installation as described in the UPGRADE file in docs folder.
Now I tried to :
1- backup the public folder and config.inc.php
2- remove all the files of the current installation folder
3- unpack the ojs-3.1.1-2 tar package in a same folder
4- create a new database and import the dump of the 2.4.8 mysql database
5- copy the public folder to the right location and adjust the config file with the right parameters.
6- start the upgrade via command line using the command : php tools/upgrade.php upgrade
and saved the command results to file result.txt
Those notices "unserialize(): Error at offset … of … bytes in " suggest that your character set configuration has changed – double-check that your new and old databases have the same encodings, and that your config.inc.php character set options match your old 2.x installation.
