There is no such thing as a persistent instant clone - do you mean dedicated instant clone? When you go back to the Inventory > Desktops page in the HTML5 admin console, what do the Type, Source, and User Assignment columns say for that pool? Source should say vCenter (Instant Clone).
If it's truly an instant clone pool: increase the memory on your golden image, snapshot it, and push a new snapshot using the Schedule button you talked about on the first "Image" page. All child desktops will get the new memory amount allocated from the golden image.
You are correct. It is a dedicated instant clone not a persistent instant clone. I have corrected my original post.
I have erased my snapshots and created a new one and am re-running the processes now. It seems to be taking longer than it did the last time so perhaps it will work this time.
Thank you for confirming the steps...I will post an update as soon as I have one.
Second attempt seemed to work. Not sure why the first one failed. Thanks again.
