Yes, it would be fine to export everything to an XML file and then import it into the new version.
Unfortunately, direct upgrade by simply installing the current version over that old version is not possible. So the best way to do it is:
- Backup your configuration to an XML file.
- If you have set Windows %TEMP% to a RAM disk, revert it to a temporary hard-disk location.
- Uninstall the old RAM Disk application and reboot.
- Install the latest version and import your XML file.
- If you did step 2, set %TEMP% to point to a RAM disk again.
It's also worth noting that the latest versions support the exFAT filesystem, which generally outperforms NTFS due to low overhead. Here is
some guidance on choosing a filesystem.
