Whether such a demo would be possible, I wouldn't know, but I personally wouldn't recommend these fitness products, because the battery life of up to 7 days is very modest. If the Fitbit Charge 5 is really necessary, okay, then that's certainly a good choice.

But there is, for example, the latest Amazfit GTS 4 Mini, a very well-equipped fitness watch that would have a battery life of up to 15 days with normal use, and up to 8 with intensive use (we don't know how long the Fitbit Charge 5 will run with intensive use, but that should be 2 to 3 days at the most). With GPS tracking, it runs for 21 hours and supports 5 different satellite systems (the Fitbit only supports GPS and the Russian GLONASS system).

A fitness watch is a great thing, but a short runtime is no fun in the long run, and sooner or later such products end up in a drawer, because the constant recharging is simply tedious.

Maybe this would be an alternative, and it would be a bit cheaper :-). And the straps are normal 20 mm straps, which you can get everywhere and change yourself very quickly (a Fitbit 5 strap costs at least 29 francs at Digitec).

I found a detailed video on the Fitbit Charge 5 here (44 minutes, but it has skip marks):

Synology also supports drive migration, of course, but there is also a migration assistant if you want to build a new NAS. I would also recommend the solution with a new NAS and new disks, because then you definitely have a backup solution in case something goes wrong during the migration (but this is unlikely).

I would definitely not sell the old NAS, but continue to use it as a backup NAS, even if the space is not enough to store everything from the new NAS, you can at least use it to back up the most important data.

Synology has also linked information here on how to migrate:
