Merging Order Hub customizations after you apply fix packs

When an environment is updated with a new fix pack, it is optional to merge the customizations onto the latest Order Hub code base.

The existing customizations work in the upgraded environment, and no changes are required. However, if you customized a route by using the customization by code method, any fixes that IBM® implemented in that route are not available in the environment. To have the fixes from IBM included, you need to merge the customizations onto the new code base.

The process to move your customizations over to the new code base differs slightly depending on the approach that you took when you customized the code.

If you used the differential customization approach, you need to recompile the code.
If you used the customization by overrides approach, you need to merge the code.

After you merge your customizations onto the new code base, you build, test, and deploy the customizations. For more information, see Merging customizations into the latest Order Hub code base.
