Hi Dear Erman!
How are you ? :) Time flyes :)
Have a  new customer with 12.2.4 + 12c db.
We want  to upgrade to 12.2.12 + 19c
What do you think :
First upgrade EBS  12.2.12 on 12c
THEN after some time db 12->19c
Or all in 1 shot.

If we do in 2 phases, then testing should be done for 2 phases separatlly as well.
12c Db we dont have extended and will not buy it  as well. How big risks to run to issues ?
I think not  quite big as the ebs level patches should cover those issues.

If 1 shot, too much pressure on hours /downtime, but  we save on testing, as tested only the final result.

What is your advice would be ?
Thx alot! :)
