I presume I could take the two discs as a RAID 1 out of my TS-262. And install them into a TS-462, add a third disc and it will allow me to migrate to RAID 5.
I havent checked my nas in a while but I think Im running Raid5(four disks, one as spare). Im only using about half of the available space, Im also the only user. My nas is mostly in sleepmode because Im a little afraid of having diskfailure due to three of the disks being ”older”. I havent had any diskfailures yet but a couple of years ago, during the pandemic actualy, one of the backplane connectors on my previous nas failed and I got a new nas as replacement since there wasnt any parts available :). My question is: could/should I migrate from raid 5 to raid 6? I know Id probably have to copy everything and that would take a while but Ive done that before
We'd always recommend doing a backup when under taking any big change like this, but yes migrating to RAID 6 will provide you with more protection (2 drives failing) than RAID 5.
“Hello, I have been adding disks to new simple RAID groups (I now have 3 simple RAID groups with one disk each). When adding the fourth disk, I wanted to create a RAID 5, but I think I can’t do it now. Is that correct? Is there any solution without data loss?”
Unfortunately no way to do it without removing the data off the disks first. You need to have a "free" disk, with no data/pools/volumes on it to be able to use it for migrating and expanding.

Yes absolutely!
Can you do this on hero?

Why dont I have that second drop down box to create the raid 1?
under the manage tab i only have Recover RAID Group as an option on a RAID 0 drive.
Which NAS do you have and how many drives are in it? To go up to a RAID1 setup you will normally need an even number of drives for it to be possible.
