Export Old Outdated Files To New Updated Version

Good Day Everyone,

I have a old version of Git that is on its own private network and want to export all items (repository, wiki, issue tracking, etc.) to a new updated version. The older version doesn’t have the exporting option. I was told that the older version is too many versions to update to the new one. The old version is 7.6.2 and the new version is 10.2.8. I don’t necessarily need the latest version, but the version that can export would help immensely. Any advise would be appreciated. Thank you so much in advance. Have a good day!
