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?
