I honestly have no clue what are you talking about, GUI does change every update, you are not recommended to import same presets from older setups since it may not contain some values or have them different from recent release, you still can by throwing old files into preset folder, but if anything breaks - that's not to me, you've been warned
Other than that you can run both apps at the same time and compare/transfer values if deem needed.
There used to be an option to export weapon build presets. I am not talking about SVM presets, i'm talking about weapon modding builds which were exported using an older version of SVM.
EDIT: I already did it manually myself
