Joomla 2.5 is a very old version. You may want to install an old version of Akeeba Backup and an old version of XAMPP or preferably Wampserver on your workstation, restore the backup copy of the website into a virtual host and run through the updates in a test environment. Once successful, restore the upgraded site from the workstation into a remote web server that runs a recent version of PHP.
The planning process includes a full review of all the third party extensions, whether they can be updated, replaced or if they need to be uninstalled. Here are the Joomla 5.1 technical requirements and the planning documents:
