I just upgrading to Dolphin 7.4.1. Next step I should start to study how to use dolphin_migration for migration dolphins to UNA.
But, on the UNA website, downloaded UNA 9 with only 4 modules. So I downloaded UNA on github:
UNA installer still forgot to detect http or https, If the site is already using https, we will see a messy page after the installation is complete.
