Well, I hope I'm posting in the correct forum. I'm not a computer specialist in networks, servers, etc. I'm a serious user of the products. I am a photographer and videographer. I used Drobo products until they went out of business, so now I'm switching everything over to Synology. I started with a Synology DS212j many years ago and I added a DS412+, also many years ago. I added a couple of Buffalo Linkstations, then a NetGear ReadyNAS104 and finally the Drobo 5N2s. Now I've purchased a DS2422+ 12 bay system from Synology and plan on adding a 12 bay expansion unit in the future. I'm currently managing about 200 TB of information in all these places, plus on some Macs and PCs. I want to move it all to DS2422+, but I can find no efficient means of moving that large of a data pool. I'm moving the Synology data to the new server by only filling it with six drives of 18 TB, then just yanking the drives out of the other servers which automatically crates a new data pool. Then I copy data from one volume to the other and this works fairly quickly as it just goes from pool to pool on the same machine. It's a bit of a hassle keeping track of what is on the new volume and what is on the old ones, but, such is life.

Once I move the data to one pool, I delete the old pool and reallocate the drives to the new pool. Eventually this will create one large pool and I can keep adding those drives to the pool to give me enough space to move the next pool I create. This will do I suppose, but once I'm done with the Synology NASs, I have to move to the non Synology NASs. Can I do the same thing with non-Synology products and expect they'll read the RAID configurations? The Linkstations each are RAID 1, the ReadtNAS is RAID 5 and the DROBOs are their own version of SHR.

Once completed it will be loaded with 18 TB drives, but as I'm working through this, all my 2 bay units have 4 TB drives (I've already moved the 212j and am working out the logistics for the 412+. It has 4 14 TB drives and the system is filled to capacity. The DROBOs are each filled with 16 TB drives, Sooner or later I will have to replace the 4 TB drives with 18 TB drives and expand the system, which takes forever. So I'm waiting to figure out how to move the other data before I make any further commitments.

Question 2: Is there some simple transfer mechanism I don't know about that makes this easy? I have read a lot online and I haven't understood a lot of it. People talk about using shared drives and letting them auto-populate which looks like it would take months and my initial try couldn't get the drives to sync. Some other folks suggest making a back-up on the second system and also letting it auto-populate. I didn't have any success with that method either as nothing seemed to want to sync.

I can use any help you can provide, but remember I'm an idiot and having much trouble understanding things (particularly syncing and UNIX vernacular) pretend I don't know any process you mention and walk me through it like a nine year old. You don't have to pretend hard, it's relatively true. Seriously, even something as simply as "copy", which I thought I knew, some folks started throwing around using CP to copy and I lost it. Is it relatively easy to SSH into one machine and then FTP files between them? And if I did, would that be fast?

Thank you for taking the time to read this.
 
Welcome to the forum!

No, this is not supported. DSM might detect the drives but it will not mount the volume for you to see it.

People talk about using shared drives and letting them auto-populate
I have to be honest and say I am not clear what this means. "Shared drives, and auto-populate".

Bottom line is this. The way to transfer data from a non-Syno box to your new box would be either by using an external drive connected to the new NAS that contains a backup of the data from your old system(s). Or, transfer via network using SMB/FTP/rsync or any other compatible protocol.

One way to try would be also to initiate data copy from the new NAS by means of File Station application inside the DSM.

File Station has a Tools menu and inside it, you will see Remote connection option. There you can use CIFS/SMB option to make a network connection towards the old NAS and mount a folder you want to transfer.

\\IP_address_of_old_nas\folder would be an example path. For the account (user/pass) you would use the credentials of the destination (old) NAS. Once the folder has been mapped, you can then use File Station, and a simple copy/paste method to transfer the data to any local folder you choose.

The transfer will be over the network so depending on the speed of your network as well as the drives/array on both devices, it might take some time to complete. Considering that 2422+ has 4x1GBe network ports by default, and 10G as optional, unless you have 10G installed, you will have to be patient.
