Migration Between Different DSMs

Unread post by thomascathybell » Sun Sep 16, 2018 1:17 pm

I am unclear about the following- in the following link, does the source NAS have to be DMS6 or does just the new DSM have to be DSM6? https://www.synology.com/knowledgebase/ ... _and_later
I want to migrate a DS409+ (DSM4.2-3259) to a new DS1618+ (DSM6). Is this possible or do I move to move all of the files manually?

If the new NAS has not yet been used, simply move the disks from old (v4.2) to your new NAS, and start the NAS. It will ask you to update DSM (to v6.2) and then you will reinstall/update packages.

Begin here...

It's always good to have a backup.

It's really bad idea!
There were so many changes at volume level between 4 and 6!
Even if it will work, you'll enherit volume limitations build in 4 and solved in 6!
Do not even try it if you care about your data!
Most likely your 409 had ext3, 1618+can do really well ext4 or even btrsfs.

Do some planning, your may have to buy a new drive for backup. But don't even try that migration! Way too many differences!
