What is the best way to make an upgrade of application version ?
Hi
One of my projects need to do the following things :
(1) Make an application migration: add some columns to table, add some PL/SQL code, add some functions...
(2) let the users work and wait one day.
(3) If it is OK we continue to work and the application migration is OK.
But if it is not OK, the project want to begin at the step Number 1 before the application migration.
What is the best way to do that ?
I think about :
- flashback,
- snapshot standby database
- backup/restore
Thanks in advance
