We’ve took over a Magento2 store which is using several (payed) modules without a working license key which wont be provided by the previous agency. The modules are created by the previous agency, so there isn’t an option to get a working license key.
Since the modules are part of the composer package, I’m unable to use composer to update and therefore unable to update Magento.
Is there a way to move the modules from vendor, remove then from composer and moving them to app/code? Without the modules the shop can’t be used since it’s part of the theme.
