Go to the "Server" folder of the previous version of callas pdfToolbox Server:
- Macintosh:
  /Library/Application Support/callas software/callas pdfToolbox CLI (version)/Server/Jobs
- Windows:
  C:\ProgramData\Application Support\callas software\callas pdfToolbox CLI (version)\Server\Jobs
Create a copy of the "Jobs" folder.
Go to the "Server" folder of the latest version of callas pdfToolbox Server.
Place the "Jobs" folder into the "Server" folder of the latest version of callas pdfToolbox Server.
