I also have a Custom Action as below.

 [CustomAction]
        public static ActionResult SetFeatures(Session session)
        {
            try
            {
                session.Log("Begin SetFeatures CA...");
                //System.Diagnostics.Debugger.Launch();
                session["ADDLOCAL"] = "ALL";
                if (string.IsNullOrEmpty(session["Installed"]))
                {
                    if (session["INSTALL_APP"] == "")
                    {
                        session["REMOVE"] = "AppFeature";
                    }
                    if (session["INSTALL_DB"] == "")
                    {
                        session["REMOVE"] = "DBFeature";
                    }
                }
                session.Log("End SetFeatures CA...");
                return ActionResult.Success;
            }
            catch (Exception ex)
            {
                session.Log("Exception occurred in SetFeatures CA: " +
ex.ToString());
                return ActionResult.Failure;
            }
        }

I use the following commands for Silent Install.

start /wait msiexec /qn /i MyMSI.msi /l*v App.log INSTALL_APP="1"
INSTALL_DB=""

start /wait msiexec /qn /i MyM.msi /l*v Db.log INSTALL_APP="" INSTALL_DB="1"

This works fine. Now during upgrade, I change the Product ID and Version. I
also change the content of the Sample text file and Sql file for upgrade.
Then when I execute the first command above, it is unfortunately upgrading
both the features. I want to control this behavior. Can anyone please help?
