I'm trying to get BEX 10 rev. 5484, installed on a Windows SBS 2003 platform and successfully using an HP SCSI drive, to recognise an additional HP external USB tape drive. The drive is included in the Veritas hardware compatability list. The drive can be seen ok by Windows. I believe I have to upgrade to BEX 10 revision 5520, which I have downloaded. Question: do I need to uninstall rev. 5484 first? If not, will my settings be transferred to the new installation? Will I need to enter my serial number again? Thanks for any advice.
