Hi, some general context on .SLReplace files:

During upgrades, files need to be replaced on the system.

When a file is still in use (e.g. a process/application is still running which has the file loaded), the file cannot be simply overwritten. In that case, DataMiner renames the previous file to SomeFile.dll.SLReplace and puts the new file in place using its correct name SomeFile.dll. This will cause any process to start using the new file after it restarts.

The .SLReplace files are deleted later on during the upgrade (or a future one)

I believe the files ".old.SLReplace" are files which still couldn't be deleted by the time a new .SLReplace file is being created.

CloudXmlWriter.dll and SLCloudBridge.dll are files which are no longer being used by DataMiner and are being removed during the upgrade. In this case, it sounds like a process is still running which has these files loaded. I believe all errors here are related to that running process. Not sure which process that would be though.

For the 10.2 CU2 version to which you've upgraded, I don't believe there is any impact besides some leftover files in the folders and the unneeded process still running.

You might be able to recognize the old process from task manager, and will probably also see it still running after stopping the DataMiner software
