Upgrade readiness check

Hesitant to upgrade Dolibarr for fear of breaking everything? Choose the target version: this module checks your installation without changing anything and gives you a clear report: how far you can go without changing anything, what would break, and an action plan in order.

What is checked:

• The code of your external modules, read file by file against the changes of each Dolibarr version: removed functions, classes and files, methods that became incompatible, functions removed from PHP… with the file, the line, the version where it breaks and the replacement.

• The PHP version at every step, and the right moment to switch.

• The database: mixed encodings, MyISAM tables, server version.

• Enabled core modules that disappear.

• Modified core files (your customisations that will be overwritten), missing or extra files.

• Computed fields Dolibarr will refuse from 23, the unalterable log key for 24, backups, the install lock…

And also: whether your version still receives security fixes, what to back up and which step will rewrite the most data, and for each problematic module, a one-click report to send to its publisher (files, lines, known fix, nothing about your company).

Measured reliability: on 45 real modules actually upgraded up to 24, all 10 fatal errors encountered had been announced.

On-screen report, downloadable as HTML or Markdown (can be anonymised, ready to paste on the forum). Dolibarr 16 to 24, MySQL/MariaDB and PostgreSQL, PHP 7.0 to 8.5. French, English, German. Administrators only.

Network: the module connects to nothing, unless you tick "Integrity of core files": it then downloads the official signature of your version from dolibarr.org, as Dolibarr itself does.

This report reduces known risks; it does not guarantee that an upgrade will succeed: always make a full backup and, if possible, test on a copy first.
