Hello,
Your ZD1000 version 9.1.0.0.38 was a patch/beta release, that was also a version
that supports ZD1100. Theoretically, you could downgrade your ZD1100 and lose
it's configuration each time you go back a version, then "restore" a backup config
you took from your ZD1000.
But realistically, it might be easier to add your ZD1000 WLAN details to your
existing ZD1100 configuration. You may have different RADIUS servers or AP
models on your ZDs today, but honestly, it would be easier to add your ZD1K
info onto your ZD1100. A merge of configuration is what I'd suggest.
Did You Know: The Ruckus Support website has a ZD debug log analyzer?
Its found in the Tools section at bottom/left of our main page. You can feed
in a ZD debug log you collected from Administer/Diagnostics page of your ZD1K
and easily see your WLAN and AP/other details to help transpose to your ZD1100.
