Well, it doesn't mention a specific version unless it's really only 2.0[00] https://www.jenkins.io/2.0/#compat >The last Jenkins 1.x release was over 4 years ago, there have been lots of >changes in that time, so expecting things to work perfect after that amount of >time is not really reasonable.

Thanks for the information. I first updated to the last 1.658 and wanted to continue from there. I checked 2.0 or so and everything still looked fine. As the underlying linux was also ancient I decided to make a completely new Jenkins Master with a current Ubuntu 20, install whatever Jenkins it has in its repositories (using now 2.269) and copy the whole Jenkins home folder from the old master over to the new. Of course the plugins were now all old and I had to update them as well. Apart from that it was quite effortless. I checked the log and found messages like this: Skipped parameter `FW_VERSION` as it is undefined on `FW_GENERIC_Copy2Desktop`. Set `-Dhudson.model.ParametersAction.keepUndefinedParameters=true` to allow undefined parameters to be injected as environment variables or `-Dhudson.model.ParametersAction.safeParameters=[comma-separated list]` to whitelist specific parameter names, even though it represents a security breach or `-Dhudson.model.ParametersAction.keepUndefinedParameters=false` to no longer show this message. I'm not sure if one of these arguments would help in my case or if it would rather mask the problem. If the problem is easily solvable then I can apply it to the current system. If not then I can also start over again as I still have the old one and if you can tell me the best way to go about.
