Starting with version 3.2c the HDD Mobility feature was introduced.
Hard drive mobility was introduced in version 3.2c as the DB is always located in the same path. While the application is loading it looks for the DB data under X:\ViconNet\DNData\DB\AVDB where X= Any windows drive letter.
If the version is 3.2c or higher you can try renaming the AVDB folder to "AVDB_old" or any name you choose and copy it next to regular "AVDB" of version on any storage drive. The path would be: X:\ViconNet\DNData\DB\
Once this has been done ViconNet should show the newly added DB folder as an archive, if this does not work please contact us.
