Re: Migrating extant system to new hardware

<snip>
I have not researched inherent limit of virtual optical but I do like that
idea of backing everything
up and transmitting an image then installing raw from the image. I've
never done that, but it really works?
Again, is there a limit to the size of the virt opt image?

It's pretty darn big if there is a limit.
Keep in mind that virtual optical is an "image catalog". Very important
term.
Each "image catalog" has multiple "image catalog entries".
I have one image catalog composed of 6 image catalog entries. Each entry
is between 1-4GB. This is just the latest PTF cume and groups.

CUME_6.bin 2,048,000K
CUME_2.bin 1,392,640K
I've done OS upgrades with a LOT more entries.

I think there's a limit of 1TB on each image catalog entry.

You might want to verify that for 7.1. Just change the dropdown on the
