vmotion

I know in theory the vmtion should work if it failed nothing will happen to vm.
In my experience nothing happened to vm when I was doing vmotion.
I have a big VM and want to vmotion, want to get some advice from tech who have more experiences.
What will happen to VM if the vmotion fails?
Will the VM be safe on the source esx?

What do you mean by if it fails?  Like if while moving it fails?  It will just stay where it is and fail to move.  It wont like split in half so you have 50% on one site and 50% on another.  Just validate you have enough space and it meets the requirements.  Also make sure the target is compatible.

I am sure the validation will happen before it moves and it will say whether validation success or fails.
What do you mean by if it fails?
I meant while it is moving .

If vMotion fails, it's cancelled, and stays on the original host.

Small or Large VM it does not matter.

The data is not moved, only the running state is transferred between hosts.

Do you want to change VM's host (vMotion) or datastore (previously named storage vMotion) ? Copy can be long if you have large data disk and you're changing datastore. But in both cases if it's failing, your vm keeps running on source.

nb : if you want to change both host and datastore at the same time, VM has to be powered off.
