ACM Migration from Joomla 3 to Joomla 4

Pedraz

Hello everyone,
I can't get any further when migrating from ACM 8.4.1 to Joomla 3.10.11 to Joomla 4.2.9.
First of all, some basic information: The server is currently set to PHP 8.0.22. It was created by me a migration of Joomla! 3 into an empty Joomla! 4 Installation performed then users, content, menus etc. with SP Transfer.
Acymailing Essential was installed on the Joomla 3 website. The Joomla 3 and the new Joomla 4 page are on my webspace for reasons of space.

My plan: first downgrade ACM Essential to ACM Starter (remove/decouple license key), perform migration and upgrade back to ACM Essential.
On the Joomla 3 page this error message was displayed when updating ACM 8.4.0 and 8.4.1, but the update was installed.
{"message":"NOT_ALLOWED","data":[],"error":true}

The ACM database tables of Joomla 3 saved, imported into the database of Joomla 4 and changed the table prefix.
In Joomla 4, an unsuccessful attempt is made to install ACM 8.4.1. The result is a white page again with the same error message.
Hope you can help me with some hints.

Hello mihha, I sent the e-mail yesterday, but did not receive a confirmation of receipt.
Now, as a precaution, I prefer to ask if my e-mail has arrived at the support?

I can't answer this because I don't know your email address that you used to open the ticket

Thanks for the info. Should my email have ended up in the spam folder?
Then I'll just send my request again.

As I said, I don't know what is your email address, and therefore I can't answer if your email is in the spam, or we received it
