This article explains errors you may experience while using the Upgrade Compatibility Tool and provides solutions to fix those errors so that you can successfully execute the tool.
When two modules have the same name, the Upgrade Compatibility Tool shows a segmentation fault error.
To avoid this error it is recommended to specify the path to the module as an argument:
bin/uct upgrade:check --current-version=2.4.4 path/to/the/module
The Upgrade Compatibility Tool may not be able to analyse the codebase if it contains circular dependency between methods.
Steps to reproduce:
If after running this command:
bin/uct upgrade:check INSTALLATION_DIR -c M2_VERSION
The only output is
Upgrade compatibility tool:
bin/uct upgrade:check /var/www/project/magento/ -c 2.4.1 Upgrade compatibility tool
The likely cause is a PHP memory limitation.
There are two possible solutions to avoid this PHP memory limitation.
Override the memory limitation by setting
php -d memory_limit=-1 /bin/uct upgrade:check INSTALLATION_DIR -c M2_VERSION
M2_VERSION is the target Adobe Commerce version you want to compare to your Adobe Commerce instance.
-m option allows the Upgrade Compatibility Tool to analyze each specific module independently to avoid encountering two modules with the same name in your Adobe Commerce instance.
This command option also allows the Upgrade Compatibility Tool to analyze a folder containing several modules:
bin/uct upgrade:check /<dir>/<instance-name> -m /vendor/<vendor-name>/
