[downgrading from 6.2 to 6.1.]

 

I was running a DSM 6.1.7 on DS3615xs for several year and recently decided to upgrade to a more recent version on DSM 6.2 in order to get benefit of new enhancements.

I managed to get a DSM 6.2.3 running on DS3617xs and get all my drives plugged back on the station.

Unfortunately the new setup was really not stable so I tried and succeed to get a dsm 6.2 running on a DS3615xs . I still had lot of problems there so I decided to move back to my original setting.

I proceed with the clean disk install with an empty SSD and succeed easily to move back to 6.1.7. This last installation looks very stable and I even manage to enable the quickconnect  that I never succeed before.

I fell then confident and plug back my raid drives but when I restart I had a migration screen from DS3617xs to DS3615xs.

I was very surprise since my station previously starts normaly from the clean SSD without my raid drives.

I finally decide to proceed with the migration from DS3617xs to DS3615xs but when I select the manual install with DSM 6.1.7 pat file I got this screen

 

 

 

and do really know how to move on.  

 

Tanks in advance for your help

[How to easily backup my data before a migration from ds3615 to ds916]

Hi, I would like to migrate to DS916, but would like to backup at first my 9 tb data (just in case.....).
Do you know the cheapest and most efficient way to backup these data in the cloud taking into account that I should not need to restore anything if I don’t have any issues.

Thanks
Regards
