how to upgrade from spine 3.8 to 4.2

I plan to import some files exported from Spine 3.8 (*.skel and *.json) into Spine 4.2, but it's not working. It must be imported using 4.2 files to work with Spine 4.2.

My problem is that I don't have the Spine project files (.spine), only the export files (.skel and *.json) . Is there any tool that can upgrade the exported files from 3.8 so that they can be imported into Spine 4.2?

lucasgo24601 As Spinebot answered, first import the skeleton data exported from 3.8 into 3.8, save the .spine file, and then open it in 4.2 and export it. The following blog post may be helpful for importing skeleton data:

If you have a large number of skeletons that you want to upgrade, it is recommended to use the CLI. For more details, please refer to the following section of the Spine User Guide:

To upgrade from Spine 3.8 to 4.2 when you only have the exported files (*.skel and .json), you will need to follow a specific process since direct import of these files into a newer version is not supported. First, you should import the JSON file into Spine 3.8 to create a Spine project file (.spine). Once you have the project file, you can then open it in Spine 4.2 and re-export it to the desired format. Unfortunately, there is no direct tool to convert the exported files from 3.8 to be compatible with 4.2 without first creating a project file in the older version.

Thank you, Misaki. The CLI has been very helpful to me, as I have around 200 Spine 3.8 files.
