Wordpress migration missing authors

I am attempting to migrate my wordpress site which has probably 30-40 authors, but only the most recent blog posts are migrating over with their authors. I tried disabling all plugins on Wordpress and exporting the json again, but I get the same results. Is there anything I can do here? Thanks!

You can confirm if the issue is on the “export” side or the “import” size by reviewing your export. Maybe it’s a JSON file, or a Zip file which contains one or more JSON files.

Search in the JSON file that contains the exported posts using a text editor. Look for some of the missing data.

If the data is not in the export, you have an export issue. If the data is definitely in the export file, you have an import issue.
