I have an OEM 11g to OEM 12c Upgrade with Exadata Targets
Documentation indicates that keeping the Exadata Target data is not kept.
Has anyone been able to work around this any ideas are appreciated.
This looks similar to below internal bug
Bug 14358781 - 12C UPGRADE CONSOLE DOES NOT LIST EXADATA PLUGIN
As per EM dev updated in the bug I don't see any workaround for this.
The 11g data of the unsupported EXADATA targets can't be used with the 12c console. So, these are being dropped and the targets are redefined.
The work-around to keep this data for later use is to keep the 11g instance around with the 11g repository to view the data. Since we can't upgrade the data this is the only possible solution.
