For many years, we have generated HPGL plot files of our Pro/E drawings and used these plot files as our long-term storage.
In addition to HPGL files, we also have a bunch of TIFF files and old Calcomp plot files (906/907 format I think).
Although this has worked adequately for us, we believe that now is the time to start using PDF instead.
Have any of you gone through this type of tranformation?
What issues did you encounter and how did you handle them?
For example, was the image quality what you expected?
Any file size concerns?
Did you mass-convert your old plot/image files to PDF?
If so, can you recommend a utility to do so?

This is -oh so dangerous- if you do not vet the process very well.
PDF's have been known to simply go poof when an error is encountered. Line weights and other details can easily disappear if the settings are sloppy. There is little control of bit accuracy when converting good data to PDF. Don't do this on a whim!
Having posted the warnings 1st, I have worked for several organizations that keep their master document as PDF. Master meaning "shared with outside resources". The true masters are still the source files although they can easily be corrupted over time with parametric dependencies. The idea is that the PDF is actually an "archive" file. If the master data -did- get corrupted, you have something to go by to re-create it.
Then you have that excellent accuracy of the vector plot files (HPGL) or the bit-accurate TIFF files. No matter what, DO NOT LOOSE RESOLUTION! Your PDF's will need to be 1:1 (minimum) accurate with the drawing.
PDF line weights can obscure details easily recovered from the vector files (you can recover DXF from vector files easily); File compression in PDF can easily obscure TIFF resolution with a poorly chosen converter.
The last note: CONSULT AN EXPERT! ...not just a salesperson when pursuing this avenue.
By the way, I go back to the Microfiche era. I've seen a lot of yes-men make really dumb decisions with all the pretty promises.
