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
