    Connecting to a 12c server from a 10g client

    KvonMurphy

      Hi,

       

      My customer wants to drop an old 9i server. It's used as a datastore by an old (barely maintened) application which uses a 10g clint through ODBC.

       

      Is a 10g client (10gR2) able to connect to a 12c server? Is there known issues?

       

      Basically : is it worth to spend time (and money...) to test?

       

      This seems to be a simple application (a bit of PLSQL, one schema, no fancy feature). If we decide to try, I'm planning to dump the schema and reimport it into the 12c, and chang only the TNSNAMES.ORA of the client.

       

      Thank you for any advice!
