Changing the PHP version of the website

The order would be to update the code of the web pages to the latest versions supported by the server you have (5.4 on nazwa.pl) and 7.4 (home.pl), and after it is updated, change the server options to the latest ones supported by the respective service provider (PHP 8.2).

At the moment, changing the options of the server itself from the supported PHP 5.4 version results in the page not displaying.

In addition, it would be necessary to upgrade the website databases on the nazwa.pl server to the latest versions (from MariaDB 10.1 to MariaDB 10.6).

Based on the above information, please provide me with a price quote for:

- update the code of 4 websites (3x nazwa.pl, 1x home.pl)

- updating the website database (3x nazwa.pl, no home.pl)

In the price offer, please include the cost of the overall implementation of the order, i.e. updating 4 websites and (optionally) the price for updating one website.
