MKS / PTC Implementer question: converting object codes

This post is very Implementer specific. If you do not use or have never used Implementer, you may want to skip this post. (I reference MKS because many Implementer users never realized that PTC bought out MKS years ago.)

"For reasons", I need to duplicate the PF and LF object codes to PFE and LFE object codes, respectively, then convert hundreds of existing objects defined with the PF and LF object codes to PFE and LFE object codes. PTC provides articles 127578 "How to convert existing object from one object code to another in Implementer" (which doesn't apply to data files, but has relevant information) and 120120 "How to convert traditional DDS file to SQL DDL files in Implementer" (which is somewhat misnamed, since it also discusses the PF/LF to PFE/LFE type conversion as well). Those of us familiar with this process may remember that part of the process of converting data file objects requires creating a backup of the "live" data, wiping out the "live" files, promoting the files with the new object code, then copying back the data to the "live" files from the backup. Fine to do in a test/QA environment, not so much in a 99.99999% uptime SLA production environment when dealing with hundreds of large files.

Has anyone found a way to do this without taking production data files offline?
