I’d also test carefully by moving media “offline” by placing the actual files in a prallel folder or by renaming the original media folder as “offline.”
I have not done what you are inquiring about since like CS3….
I had some bad experiences back then coming from HDV (firewire not RS-422) with frame drift +/- 3 frames per clip.
DV seemed to work ok which led me to believe that it had more to do with the GOP structure of HDV than anything else.
I also was put in charge of conforming an offline around that time in a system equipped with a capture card and using 422, but I think the initial capture had a timecode setup versus the actual frame rate on the tape that cased some problems….
so….just do you diligence and check yourself on a few tests before you commit.
