I tried to migrate a my catalog in Lightroom Classic v.10 to Lightroom and I went through the steps and no pictures migrated. So I deleted the new catalog in Lightroom and thought I would try again. Unfortunately now it tells me that that catalog could only be migrated once. Not sure what to do now.
I have about 8,000 photos in about different folders/collections that I want to migrate. Any help on how I should proceed would be appreciated.
