VCSA migration

Can a VCSA migrate itself while running to a different host?  I would think no, but I am just guessing.

vSphere 6.7.0 environment.

Thanks!

You mean vMotion (migration) If so then yes of course it can. :)

In fact on my test network I run VCSA in the local storage on one host and can vMotion to the another host and storage migrate it to local storage on that host with no interruption of service.

Well, isn't that slick.  I'm even more impressed with it than I was before.  Wow.  Thanks, Pete!

and if you have DRS and Storage DRS, VMs move all day every day.... across hosts and storage......in real time with zero downtime!

You never used vMotion ? and vMotioned a Live Streaming Windows Server Live Streaming TV to clients????

Does not even miss a beat...... (and it's only got better since 2.5!)

No worries, obviously you need cluster with vmotion enabled and licensed.

Ben Pete is correct you can vmotion the vcsa to any host while up and running I use to do that also but now I have my vcenter setup using HA which creates two more vcsa peer and witness they go on different hosts look into HA

Been a long time since I took the intro class.  I do have vMotion, etc. but didn't have the hardware until recently to implement a decent structure.   I'm probably to the point I need advice on how to restructure this.  Will create a diagram and post it in a separate question.

Thanks to all!

If it's not an experimental lab you are building, the design should be confirmed on paper before you build it, because changes later to a Production VMware vSphere infrastructure could cause unnecessary downtime.

Which is why we get so many questions later, and VMware Admins telling me " cannot do that because it's in Production!".

To which I reply "should have been designed and tested correctly before production"

Copy that.  

That's why years ago I picked the simplest configuration I fully understood.  Well below what was technically possible but didn't have the hardware or licensing at the time.   Now I do for the most part (I think) and have grown to where I need to do it in a more efficient manner.

Ben,

Looking forward to helping you on this.

How many esxi hosts do you have or plan to have?

How many VMs are you planning or have now.

Hi Thomas,

Right now I'm good with 2 hosts.  In the future I may add a 3rd off-site host for a complete failure mode here but that is down the road for 6-12 months at least.

I have about 20 hosts, most of which are low-volume activity.  Couple of SQL Server databases, one mail server, a few web servers, Active Directory server, a Wordpress server, etc.
