You can run Spine 2.1.27, use Import Data
, save a .spine
project file, then you can open the project file with any newer version of Spine (I suggest using 3.8 ). Note that how scale and flip are applied has changed, so you may need to fix up your skeletons:
Blog: Spine 3.0.00 released

GitHub - EsotericSoftware/spine-runtimes at 2.1.25
