Is it possible to refresh a vDB that has been upgraded to a higher Oracle binary version from a dSource that is still on the older version?

For example -

TEST1 is the dSource and is on
vDBTEST is the vDB that was created @ but has then been upgraded to

Can I refresh vDBTEST from TEST1? Would the binary revert back to

Hi Jimmy,
Currently we do not have a rewind a VDB feature, though there is an open request for this that we are in the process of working on for future versions of Delphix. There are some workarounds to do this, if you haven't made any changes to the VDB the easiest thing would be to provision a new VDB from the point in time from before the upgrade. If you have made changes, a VDB is an Oracle database and you would be able to downgrade just as you would an Oracle database (this Oracle Support article might be helpful); though if you do this you also need to use the process in Upgrading an Oracle dSource so that Delphix picks up the new Oracle binaries. 

Hope that helps!
