Oracle upgrade 12.2 guide says
"If you are upgrading from Oracle Database 12c release 1 (12.1) to 12c release 2 (12.2), then Oracle recommends that you drop the JSON-enabled context index before upgrading. Oracle recommends that you drop your existing JSON-enabled index.
If you created a JSON search index using Oracle Database 12c Release 1 (188.8.131.52) then Oracle recommends that you drop that index and create a new search index for use with later releases, using CREATE SEARCH INDEX statement. Please refer "Oracle Database JSON Developer’s Guide" for more details."
