Hello, dear @Olariu Romeo Vicentiu !

I would like to address the ongoing discussion in a more organized manner, considering its unexpectedly extended duration. Kindly take note of the following points:

All issues pertaining to the Dolphin migration script have been brought to the attention of @Alexey in a separate thread, where they are being actively addressed.

I appreciate your proficiency in working solely through SSH. However, the request for "CPanel access" is a common procedure employed when there is a need to inspect server-side components. It is worth noting that not all website owners possess the same level of expertise as yourself, and CPanel offers a more user-friendly interface for their benefit.

The recommended approach for working with UNA involves utilizing Studio. Consequently, the installation of the Dolphin migration tool directly from there was not possible. Nevertheless, it serves as a valuable internal resource for facilitating migrations, which is why it has been retained in our GitHub repository. For the optimal workflow, I suggest following the step outlined in the documentation available at https://una.io/wiki/Installation#step-1---download.
