Thank you for answer.
Yes, I know the process of renaming tables.
If the thread_entry_email_new table is not filled with data, the resulting table will also be empty after renaming.
Therefore, I want to fill it manually, comment out the code for creating and filling the table. Then I can run the upgrade.
I just want to avoid unfunctionally filling the table with data.
The only thing I'm missing is the content of the email_id column. Therefore, I would like to repeat the questions: What data should the email_id column be filled with? Are data added to the email_id column until after the update?
Refresh doesn't work. The page keeps loading but never loads.
Additionally, it would show an error that the table thread_entry_email_new already exists.
