Hi Adam!The usual downtime for this should be a weekend.For the GoLive you can prepare a lot in advance instead of doing all single steps of the whole upgrade again. I think it is most important to understand what can be done upfront to the downtime window and what are the real downtime actions.We've been doing EBS upgrades for years now. And we also have experiences in upgrading to 12.2.9, 12.2.10 and 19c. Feel free to contact us. Happy if we can help here!Hint:Review the following notes:
