I'm trying to upgrade some files in our EPDM, and no matter how I configure the tool, I keep getting the message below. I've tried logging in as admin, I've tried having the files checking in/checked out, I've tried adding variables, I've tried setting it to overwrite the current version, create a new version. I've changed the location to save the log file to a pdm folder/then a local folder. I've checked and double checked that the folder I am selecting to upgrade does indeed contain files that are saved in 2016, we are trying to upgrade them to 18. Is that the problem, can you not skip a version with the tool maybe? Any ideas would be greatly appreciated. Thanks in advance.
