      Instructions

      Marco's Recommended Instructions are as follows:

      • Backup System
        Before upgrading, go to Options> Backups and click Export now, to make a backup of your database just before upgrading. 
      • Verify Version
        Then go to the About tab and write down your current app version, example would be “Version: 22.0.3 (Build xxxxx)”. This is to ensure we’d know what version your database backup matches in the extremely small chance there’s an issue during the upgrade process.
      • Check for Updates
        Click “Check for Updates” and download the latest version. Copy that file up to your PaperCut application server and remote into that server.
      • Run Application Server
        Go to windows services and stop the “PaperCut Application Server” service. Then run the upgrade file right in place on the PaperCut server, right over the top of the existing installation. NOTE: Depending on how old your previous version was, and how big your database is, the upgrade could take anywhere from 5 to 60 minutes.
      • Print Server Consideration
        If you’re running a print server separate from your application server, copy and run the same file up to your print server(s), making sure the “Secondary Server” option is automatically selected during the upgrade process.
      • Test and Verify
        Once completed, do a cursory test of all functionality. Log back into your PaperCut admin web page, make sure it’s up and running, and doesn’t alert about any database issues. Log into an MFP, release a print job, perform a scan, etc. If an MFP is behaving oddly, give it a reboot, and if that doesn’t fix things up, then please reach out to Marco.
