Howto downgrade from 6.1 to 5.2 IN ESX

Recommended Posts


i am playing around with 5.2 in ESX, i am going to update to 6.1 , i will start with a clean VM, probably the DSM software will be replaced on all raid/disks


what if i am not happy with 6.1  and want to go back to my 5.2 VM

can i just boot it up again, when i attach the controller that i passthrough

because if i fireup 5.2 with this file again =  XPEnoboot_DS3615xs_5.2-5967.1 , it will notice that DSM 6.1 was installed 


so, how can i downgrade in an ESX system from 6.1 to 5.2 without loosing data? :smile:

this should work in esx as well as bare metal

but i would test with a couple of new vms for 5.2/6 before you do your live system, plus have a backup
