Hello Listers, With respect to having a safe upgrade(say from 11.2 to 19C) or migration(From HP to Exadata) experience with minimal performance issues. Is there any guideline we should follow like setting up exadata system stats in case the target database is going to be exadata, Or verifying dictionary stats/table stats etc in a certain way. Want to know experts' views, if there are any such guidelines?
Regards
Lok
In my position, I talk to customers/prospects going through similar upgrades/migrations and those who follow(ed) Steps 2 and 3 (and understood the differences) had SIGNIFICANTLY better success than those who tried to “shortcut” the process.
