Yes, it is possible to migrate a plugin from a development server to a live server. There are various software tools available such as Backup Buddy or Snapshot that aid in migrating between servers and domains. However, it is essential to update the Site URL settings manually if they are not taken care of by the migration tool. This is especially important if you are moving the files and database tables manually. If you have any problems the team at Radial Payments is here to help.
