It is considered a best practice to uninstall any previous versions of the OnBase Epic integration components before upgrading to the latest version.
If you are upgrading the Scan Acquisition Server or Front Office Scanning integration from OnBase 13 or earlier, you must uninstall the files from the previous version. In OnBase 13 and earlier, the versioning for certain scanning files is different from later OnBase versions. As a result, these files cannot be upgraded by the installer. By uninstalling the scanning integration files before performing an upgrade, you can ensure the correct version of the files will be installed.
