Thanks, @cjyabraham! I think that’s what I am missing. I see that the IDs don’t match between the old and new sites. It seems like exporting the users and users meta tables directly is a better bet than using an export/import plugin.
Trying to do the same thing here. When I upload the photos via FTP to the new site, the photos aren’t associated with the correct profile. Any thoughts on how to get the photos to associate correctly?
