If you are in the source application and navigate to System > File Explorer and choose the "Export all application database files to file share" it will create XML files of each of the artifacts. Then you can use the "Import All Application Database Files" to import them back in. This and the File Explorer Manager are going to be the tools that are available. The files will get exported out to the OneStreamShare\FileShare\Applications\<appname>\Internal\ImportExport\ directory and then you can select them all and copy them to the target application that you want to import them into under the OneStreamShare\FileShare\Applications\<Targetappname>\Internal\ImportExport\ and then use the "Import All Application Database Files" and it will import any files in this location into the file explorer of the new application.
I would recommend testing it first with copying just a couple files and make sure they get created as you expect and then you can complete them all.
Hope this is helpful.
