Lifespan of Synology NAS

[Mike48]

While my RAID array is rebuilding, I'd like to return to an earlier question: whether a HDD set can be moved from one Synology device to another, and how.

Soon, I'll have four new IronWolf Pro HDDs in my DS414. But what if the DS414 itself fails next week? Would it be possible to move the whole disk set into a new model and call it good, or should I move them, set up a new array, and restore from backups? It would be far easier to do the former, yet my impression is, it might not be a good idea. Comments?
