A custom composer configuration has been detected which is incompatible with the upgrade process.

Question

Good Day! I would like to ask for your assistance regarding my SugarCRM Pro 7.7.2.0 upgrade issue. I am trying to upgrade our existing SugarCRM Pro v7.7.2.0 to v7.7.2.2, but I cannot proceed due to an error I encountered. Already reported this issue to Sugar Support with Case # 473082 , just trying my luck if anyone encounter this error too.

I experienced the same issue upgrading from 12.0.3-to-12.0.5 , see logs below What worked for me was downloading the stock installation file for v12.0.3 ( SugarEnt-12.0.3.zip) and extracted it to get the stock composer.json file from the version i was upgrading from (12.0.3) and replace it in my current instance in the main sugar files folder. Afterwards, the upgrade process went smooth, all the way to upgrading to v14.0.
