Which is why GP talks about incentive. What technology is your "system/website/app" going to use? Who's incentivised to update it? Who migrates to something else when you abandon it? How much does all this cost compared to non-digital records, which have almost certainly been kept, but some lost due to a lack of incentive to keep them up to date and safe?

Laws are written down to make them as permanently-accessible as possible, which acts as defense against capricious rulers. Anything that makes them less permanent is a small blow to the rights of everyday people.
But I understand that the British system isn't built that way and instead of creating a consolidated "constitution" rather enjoy the fun of a Speaker citing some old precedent, which nobody can know about. True excitement.
This precedent certainly doesn't come from vellum, which GP misses.
The 'precedent from 1604' was that parliament couldn't be asked to vote twice on the same matter in the same sitting; but that isn't archaic and disused, it's common practice and Bercow (and other members) quoted numerous occasions on which speakers had disallowed votes on its basis.
Your link is about Bercows 'unprecedented ruling' giving MPs more control over the business of the HoC, as opposed to the Government.

So, ok, thanks - I take back the 'not actually migrated' part, but I still think it serves as an example of not-technology lasting successfully for a very long time, and the replacement is... a different paper technology!
Digitizing everything helps, but the enemy is still volume, time, and money, and digitizing costs even more money.
