Upgrade the UCO from previous versions

Note: If you are upgrading MES application objects to the current version of MES, the version you are upgrading from must be MES 2012 (version 4.5) or later. If your version of MES is at a version prior to version 4.5, you must first upgrade it to version 4.5.

When MES is updated from a previous version, you must import the new UCO into the System Platform IDE. Each version of the UCO is compatible only with the MES version with which the UCO was shipped.

1. Undeploy any System Platform galaxies that have UCO instances before installing the new version of MES.

   This ensures that the System Platform IDE is disconnected from the MES database and any MES components.

2. After installing the new version of MES, import the new version of the UCO into all the galaxies containing an old version of the UCO with the Migrate option selected so that all existing templates and instances will be updated.

3. Before deploying the objects, make sure that all MES application objects—OCO, SRO, and UCO—are at the same version and that their existing templates and instances have been migrated. Otherwise, incompatibility errors will occur.
