What to do next

  1. Remove unnecessary files from 3CX backup, so as to reduce file size and improve restore efficiency.
    1. Optional: Create a copy of 3CX backup.
      Note: It is recommended to edit a copy of the downloaded backup file, in case the original 3CX backup has retention value.
    2. Delete unnecessary files from the backup (or the backup copy), keeping only the httpprompts, vmailprompts, and .xml file.
      Important:
      • Do NOT unzip the backup (or the backup copy) to make changes and then re-zip it. All deletions must be performed directly within the .zip folder.
      • Do NOT create any new folders in the backup (or the backup copy). Retain only the listed items; otherwise, the restoration may fail.

  2. Restore the 3CX backup copy on Yeastar Phone System.
