Basically it boils down to...exactly the same as in on-premises: WLST scripts.
Ah, very good. I know how to do that. Thanks, Christian.
Don't overthink things in OAC. It's stil based on the OBI core tech so most of the things from on-prem can be made to work there too.
Yeah, I need to keep remembering that, Christian.
So, now I'm using the same technique that I used in 11g and 12c on-prem, launching :7001/console, going to Security Realms, myrealm, Migration, Export, and I am exporting the identity store from system #1. Then I'm transferring the generated files to system #2 and doing an import.
Everything except the passwords appears to come across. I see a bunch of new users, display names look good, and so forth. But the passwords are all empty.
In the export file (DefaultAuthenticator.dat), my own entry looks like this:
displayname: Mark Thompson
So there is an encrypted password in the .dat file, but the password did not make it into OAC.
I cannot seem to delete the previous comment (i.e. passwords don't work). Passwords DO work. It would help greatly if I would have typed my password correctly. This WORKS!!
As long as it works all is peachy
