There should not be any need in a backup/restore cycle. Upon installation, NetWorx v7 detects version 6 database (.DB) and upgrades it to version 7 (.DB3).
If you have uninstalled version 6 prior to the installation of version 7 and chosen to remove all the data and settings, it will obviously not happen. In this case, the following workaround should help:
- Quit NetWorx v7 if it's running.
- Press Win + R and open %PROGRAMDATA%\SoftPerfect\NetWorx.
- Delete any NETWORX.DB3 file that may be there.
- Copy your NETWORX.DB file to that location.
Then launch NetWorx v7, it should detect the old database in place and convert it to the new format.
