RE: deleted manually the old databases but on the new import the images/logos didn’t import.
How did you migrate the source site’s Connections data to the destination?
RE: any way to do that only?
You could use the CSV Export tool on the destination site, fill in the image/logo URL/s from the source site and then import the CSV file on the destination site. This should have happened if you migrated the data using a CSV file. If you migrated the site by moving the tables from one site to the other (what I assumed you were doing), you only needed to Copy the
connections-images folder from the source to the destination.
Hope this helps!
