Reverting from Informix Version 14.10

You can revert to the version of the database server from which you migrated. When you run the reversion utility, you specify the target server for reversion and then Informix® checks your database. If necessary, Informix might tell you to drop new objects, before automatically converting your data into the target server.

If Informix cannot revert a database, Informix prevents reversion.

Normally, reversion takes only a few minutes.

If you used the new features of Version 14.10, reversion time is longer, because you must prepare your database and data for reversion, and you must remove the features that are not supported in the earlier version of the server. The more work you complete in the new version, the more time consuming the reversion. See Preparing to revert before you revert.

If you did not use any of the new features of Version 14.10 and you did not complete much work using the new server, you can run the reversion utility and modify the values of the configuration parameters. See Reverting from Informix Version 14.10.
