Plenty of threads about this matter!
Anyway you can read C:\AVEVA\Plant\PDMS12.0.SP6\Manuals\Docs\PDMS User Bulletin12.0.pdf Chapter 2.5 Upgrading from PDMS 11.
In particular Chapter 2.5.2 Performing the upgrade process
' UPGRADE PROJECT TO LATEST '
As far as I know the correct syntax is DBUP PROJECT TO LATEST.
This is for upgrading from 12.0 to 12.1 as explained in the 12.1 PDMS User Bullettin
