Hello Jim,
if you want to backup the backup exec database then you just need to shut down the bews services and mssql$bkupexec service and copy the BEBD* files under the Data folder of the program folder of veritas backup exec.
If you are intending to just manually uninstall the exiting bkupexec msde instance and reinstalling it with the name mentioned by you, we suggest you to completely uninstall BEWS and reinstall it as you wish to.
In that case we suggest you to make a copy of the following:
a. C:\Program Files\VERITAS\Program Files\Backup Exec\NT\Data
b. C:\Program Files\VERITAS\Program Files\Backup Exec\NT\Catalogs
c. C:\Program Files\VERITAS\Program Files\Backup Exec\NT\ECM
d. C:\Program Files\VERITAS\Program Files\Backup Exec\NT\IDR (if present)
e. C:\Program Files\VERITAS\Program Files\Backup Exec\NT\Reports\Saved
f. Backup-to-Disk folders as mentioned in step #4 above (if created)
Regards,
Ashutosh
