Upgrade from Ultra6 (6x2TB) running OS 6 to RN426 (6x4TB)
Hi all, A couple of days ago I bought a RN426. Yesterday I ordered 6x4TB HD's. I have an Ultra6 with 6x2TB running OS 6. I want to move all my applications and data from the Ultra 6 to the new ...
I do not have the space to do a backup. That is why I will keep the Ultra 6. It will serve as a store for the backup of the RN426. Taking that into account, I should probably do a clean install.
Yes, I mean apps runnig. E.g. Owncloud, MySQL, NZBGet, PHP 7.0, Gittea, ...
The last option looks attractive.
What I do not like about is, is the time it would take,
Is there a guarantee that I will not destroy the original disks when I put them in the RN426?
Or should I try to build the new drives on the utlra 6?
I could also install the apps on the new machine. The only thing I consider cumbersome is Owncloud.
It has some of its data in the SQL database. Ans I would like it to stay up and running for as long as possible.
Isn't there some kind of migrate from old to new function that preserves the old disks and copies everything to the new NAS / disks? Including the software. E.g. something like an image copy of a diskdrive?

I don't know about guarantees. But migration has worked quite well with OS-6. I do suggest either matching the OS version on the two NAS before you begin, or alternatively upgrading the Ultra to 10.6.3 before you migrate.
Expanding the volume on the Ultra will probably take longer than expanding it on the RN426.
It is wise to have a backup before you migrate (or manipulate disks).
While I take Sandshark's point on the benefits of starting out clean on the new system, if you have a lot of apps it's probably simpler to migrate the disks.
The SQL databases used by some of those apps are difficult to migrate. I've moved more than one OS6 volume from an upgraded legacy NAS to a native OS6 one and have not seen a problem. I didn't do it to an ARM based syustem, but neither are you.
The Ultra is only capable of SATAII and has a slower processor, so moving the volujme to the 426 before replaciong the disks should be faster. Maybe not a lot faster, since the spinning drives can't keep up with SATA3, though the cache can, and the dfaster processor will definately help.
I did fail to mention that this method means you should make a backup first (if you don't already have one). It's going to put a lot of strain on your drives, and if one or more are close to failure, this could push them over the edge.

If everything is stored in the appropriate subdiirectory of /apps, then you can copy the data from one NAS to the other. If you use the admin credentials to connect, you can see the /apps share. Since you will still have the old NAS running the apps, it's worth trying. If it fails to work properly, you can always uninstall and re-install the app to get a clean start. One issue here is that the contents of /apps noramlly belong to root, and copying in this way will make the opes on the taget NAS belong to admin. Whether that will make a difference depends on the app.
If you are adept at the Linux CLI via SSH, then using an rsync command would be best, as it can retain all file attributes and root ownership. With a CLI command, you can use RSYNC to copy things in shares that the ReadyNAS does not support with an RSYNC server. Just Google it, it's standard Linux.
Make sure you install the same version of all apps and copy the data before you restore the configuration from the old NAS and do both before you attempt to run any of them. There may be some configuration files outside of the /apps folder that the configuration backup should copy..
When you are done, we'd love to hear of your success or failure with specific apps so others can learn from your experience.
