Is it possible to recover data created with an older version of Heredis?

Yes, if you are using an earlier version of Heredis, you can simply open the file with the new version. It will then be converted automatically.

See the article Open an existing Heredis file.

Avoid using a GEDCOM file if you have a file in an older version of Heredis.

If this does not work, write to us via our contact form and we will convert the file for you.
