DIRECT ANSWER
What you should know
An unsupported-version message means the destination does not recognize the VERSION value or the way a field is encoded. Convert a copy to the documented target, then test it.
Before you begin
- Keep an untouched copy of the source export.
- Work on a small sample before changing a complete address book.
- Review the downloaded file before importing it elsewhere.
Find the destination's expected version
Look for the current import documentation or a small export produced by the destination. Its own export is often the clearest compatibility fixture.
Convert with warnings visible
Choose a target such as vCard 3.0 only when it matches the workflow. Review parameters, repeated properties, and unknown fields that may be dropped or rewritten.
- Keep the original VCF.
- Inspect VERSION values in the source.
- Convert a working copy to the destination target.
- Validate and test a small import.
Do not equate acceptance with fidelity
An app may accept the converted file and still omit photos, notes, or custom fields. Compare representative contacts after import and keep the source archive.

What should I verify after Why an App Says the vCard Version Is Unsupported?
Compare counts and representative fields, validate the generated copy, and test a small import before processing a full address book.
