Hi Don,

The ASA 8.2(1) image is about 15.5 MB and ASDM 6.2(1) 11 MB, so you'll need at least 26.5 MB worth of free space (check 'show flash') in your flash before upgrading.

As for DRAM, 8.2 certainly uses more of it than previous versions, so if your memory utilization is already high (check 'show mem'), you might want to consider an upgrade kit.

Hope that helps.

If you do a show memory on the device and if it has less than 20% free, Cisco recommends to upgrade the RAM
