I have never deployed a VM image for production and have always fresh installed from scratch. It takes me about 30 hours elapsed time to have a 12.2.6 instance up and running on good hardware. Are you deploying production on the 12.2.4 Vision VM template?
Assuming that the image has been downloaded, the installation/cloning may take 6 hours more or less
We are deploying on actual PROD servers (HP, Lenovo, Dell) both Virtualized and bare metal. We clone the image of EBS 12.2.4 or 12.2.6 from image provided by Oracle.
Before, the VM template is availalbe in edlivery (EBS R12.2.4). But now EBS R12.2.5 and EBSR R12.2.6 in only available it Oracle Cloud. We istall in on cloud and clone it, then download it to our local servers. So far it is working best, compared to what I did when using the tedious full install process which I encountered lots of error.
What I want to clarify is, if this process is certified by Oracle?
I don't think Oracle intended it to be used in this way. You should open an SR and check with Oracle support if this is supported and you may also want to check with their license team if this is even allowed from their licensing perspective.
Thanks Handat and Michael.
