Generate plesk backup from plesk control panel and then download the backup file from plesk panel in server where you want to restore it, then create reseller or clienr or domain with same name and username as previous server and in backup section of destination plesk panel upload backup file downloaded (doing this in remote desktop of respective servers can save a lots of time)once uploaded just hit restore and see magic
ps: correct ip status in both servers and make it as similar as possible before taking backup and restore
