24 TB VM difficult migration
-
Hi, I would like to get an advice to solve an annoying migration.
The VM has a 700 GB system disk on local storage and a 24 TB i-scsi storage (with 12 x 2 TB virtual disks).I want to move both VM and datas to a newer App server and a newer NAS storage. Everything is connected via 10 GB Nics.
All my attempts of live migration have failed after 3h30mn with an error message (insufficient temporary space on source).
I found on an old Citrix board that 200% free on source and 300% free on destination are required to perform successfully a live migration.So, the remaining option is cold migration. The downtime could be 3 or 4 days because the Synology rackstation is not that fast on contents with small files. This appears unacceptable to the customer.
Can I use a warm migration instead ? or does it requires a lot of temporary space ?
Regards,
Laurent

Hi,
You can use the warm migration in your case, yes
To me, that's one of the use case where it's safer than a live/hot one.
