Re: 5.3 to 6.1 on Small 520 - DVD or Image Catalog?

Thanks Everyone, Image Catalog it is.

Disk Space is fine as I just added the 2nd pair of disks and an additional
2GB of memory to get it where it is today. With the 5.3 CUME, V6R1, V6R1
CUME and Groups PTF images loaded the system is at roughly 50%. After I get
the 5.3 CUME applied I delete that.

Also at the 6.1.1 on the images.

From my experience, the DVDs are still slower. I did a few DVD

upgrades on systems sized exactly as you said, because there wasn't
enough space for the image catalogs, and also on some where there was.
The problem is that the DVDs are not optimized - the data can't be
read sequentially by the install process, the DVD drive is seeking
constantly, which is WAY slower than hard drives.

If IBM had optimized the DVD for installation, it's quite possible
that it would be faster than when using image catalogs. As such, your
only critera should be free space - if there's enough for image
catalogs, go with them.
