ok, i have instaled UNA 12 and traing to migrate from Dolphin 7.4.2,

1. Profile: The number of profiles transferred reported by una does not coincide with those reported by the DOLPHIN MIGRATION SCRIPT wich reports a wrong diferent number.
2. Album: No album has been transferred Photos without albums have no meaning anymore, they are all mixed up. Mixed salad, brand UNA
3. Avatar: The avatars are not transferred,
4. Timeline: The timeline was only partially transferred. only 5 items per profile the posting date from the old dolphin 7.2.4 does not coincide with the posting date from 12, UNA reports the posting on the same day as the transfer on the timeline. This is really not the timeline anymore
5. I have not yet reached the video and other modules, but it seems that this script is not functional.
6. Messenger: UNA 12 report It is not possible to install the current version of messenger in LUNA 12, so I cannot transfer conversations from messenger.

CONCLUSION This upgrade script does not work. And UNA has compatibility problems with the modules on his "platform". That means almost 70% of 15 years of lost work. So is not possible to migrate from Dolphin to UNA. I think it is better to migrate to drupal, here I wasted three days for nothing, and no one has an answer to my questions.
