Currently our company are trying to upgrade Primavera P6 EPPM v7.4 to v15.2 or v16 (using Microsoft SQL database) because it hard to find Primavera P6 consultant in our area, my management ask me to do the upgrading process. I am not an IT guy. So due to the huge gap between those version, I afraid if we upgrade the database incorrectly some error or problem will occur. Does anyone have experience any problem when you upgrade your P6 database? I tried to contact Oracle throught thier help line but didn't get any feedback until now.
I wish to get help as soon as possible.
