We have a project that vendor provided a SharePoint solution in their environment, we would need to back up the site and restore to our environment. We identified that their SharePoint version is different than ours. Here is the quick way we could restore it to different version of SharePoint.
- Download HXD editor
- Open the backup file
- Locate the version number and change it
- Save the backup
Now you could restore it to different SharePoint version.
If you restore the backup to higher SharePoint version, you could also attache the database, mount the site, and upgrade it.
