DSM 6.2 Migration from 920+ to 1522+

So currently i have DS920+ running with DSM 6.2 version. I havent upgraded to newest version because its working fine and there was no need. Also i have some configurations for docker + plex and roon server running on it. Was afraid to upgrade and have issues with some of apps.
All 4 bays are taken with 4x8TB ironwolf pros in SHR-1 raid.

I want to expand hard disk capacity by getting 4 or 5 exo drives 20TB along with DS1522+ because it should be faster and more future proof. Dont need HW transcoding.

1. My question is about migration and not to loose data in progress. Whats the best and probably safest way to migrate and in what order?

2. Do i configure new DS1522+ with new 20TB drives FIRST and run them example SHR-1, then migrate from old NAS using migration assistant tool?

3. Can i migrate from 6.2 to 7.2 DSM into new synology directly?
 
I would recommend you pull all existing drives and move them in the the new DS1522+. The CPU on the newer model is pretty fast and will aid in updating, rebuilding and expanding. This is the fastest uptime solution to prevent any end user disruption.

From there I would start replacing disks and allowing them to rebuild and complete before moving on the the next 3. The add your last drive and expand in full. That's pretty painless and only real downside is time in between each step.

I have done the above method when I went from my DS415+ to my DS918+ nice and easy with almost no downtime.

However when I went from my DS918+ to my DS1819+ I wanted to start fresh. So what I did there was to set up the 8bay unit as new and fresh. and use Drive Sync to copy all of my data over to the new FileSystem. I did not want to pull and upgrade from a 9 year old initial install.

This game me a chance to change anything that I had learned through out the years and trim some of my unneeded storage. Importantly it also allowed zero end user interruption as the original until still did it thing without even turning it off.

Once my data was moved over, and user accounts synced over. I changed the DS916+ machine name, IP and quickconnect ID from DigitalBanditNAS to DigitalBanditOLD, renamed the New unit DigitalBanditNAS and put it on the same IP. Router rules stayed in place, and every one using apps. did not have the change addresses or QC ids.

I relegated my DS916+ as a backup target and I have been happily moving along.
 
Thanks for fast reply. I didnt think about that to move current drives into new and then hot swap. Great idea.
However i would want to upgrade to DSM 7.2 on new NAS after switch. If i do that way i just have to hope all apps will still run.
 
IMO the more straightforward and less time consuming (and less risky) approach would be to purchase the new drives along with the DS1522+, configure your storage, then move your data from the 920+ directly to the DS1522+.

Directly? But does that work with all the DSM configurations included? I thought i have to use migration assistant or hot swap method to rebuild
 
The DS1522+ will be running DSM 7.x, so you'll build it from scratch. When ready to migrate data, you can mount a CIFS shared folder created on the DS15222+ onto the 920+ and copy over all your files/folders directly from NAS to NAS.

I do recommend drive Sync, it's automated bi directional so you don't have to babysit it so much.

Since no one else has said it, and don’t want to assume, the first step is to do a full backup of 920 before you start.

I decided to go safe and migrate to new NAS with new HDD's leaving old NAS as it is. It is slow approach but that leaves 920 as backup with just temporary profiles. I already know i have to manually fix roon server with 7.2 because of root permission changes compared to 6.2
