Yes, we have backups on the VM level, so we need to get the wordpress files out and replace them. I hope that files from 12.11.2024 02:00 will be still at 6.6 version before upgrade. Doing it right now actually.
Those questions are targeted mainly to the dev team and their management. But I just wish more people would ask these questions and put some pressure to resolve this issue as quickly as possible.
