FWIW, you can put the new card in the KLN-94 before the effective date. The old data will be used until the
effective date. If you are using it at 0000 UTC on the effective date (6pm CST) it will give you a message,
telling you to power off and back on to use the new data.

How does this work?

Does the KLN94 have enough internal FLASH to store a copy of the
complete previous CF FLASH card?

Does each CF card contains two sets of data; one old and one new?

No documentation to support the view, but I believe the KLN94 has
enough internal flash to hold two sets of data. It checks the card
inserted into the unit and downloads it to internal if the card
doesn't have the same (whatever they compare) as the internal data.
When it comes time, the unit then swaps over to whichever bank of
flash it needs uses depending on effective date (or just whatever has
the newest effective date if everything onboard has expired).

This agrees with my experience. The "downloads it to internal" step takes 5-10 minutes, but the "swap over to
whichever bank" is just the standard power-on sequence (30sec or so)...
