800xA Freelance Tag export from lab to site - best method

After Freelance CBF Engineering I have generated a *.PLE file with the newly created tags and imported these into 800xA Aspect server in Engineering Lab setup. Several non standard customizations have to be done for each tag after import. My question is how to replicate this at site with minimum effort.

1. If I export the tags in 800xA Aspect Engineering Server using export tool and import to Production Server at Site will it work? This will by pass need to do the Tag specific customization.

(OR)

2. Do I have to redo Freelance CBF engineering (This has to be done at site as well) and then re-import the *.PLE file in Site. Then REDO the customizations in site (This is what is time consuming and is difficult to do using Bulk configuration Manager also).

Please
