Downgrade from BIG-IP 10.2.3 to 9.4.7

So, yeah, first bump in the road. when I run image2disk --format=partitions BIGIP-10.2.3.112.0.iso, I receive the following error

 

 

info: Repository tm_install version/release is 2.7.2/17.0

 

info: System tm_install version/release is 2.7.1/23.0

 

info: Updating system tm_install files from BIGIP-10.2.3.112.0.iso

info: Installer on image is newer, reexec

 

info: Running updated installer.

 

info: Platform id is Mercury

 

Terminal error: Media has multiple products. Install product must be specified.

 

 

 

 

The output from a switchboot -l tells me:

 

 

Current boot image:

 

HD1.1 - title BIG-IP 10.2.3 Build 112.0

 

Default boot image:

 

HD1.1 - title BIG-IP 10.2.3 Build 112.0

 

Available boot image(s):

 

HD1.1 - title BIG-IP 10.2.3 Build 112.0

 

HD1.2 - title BIG-IP 11.1.0 Build 1943.0

 

 

 

Since we need to downgrade to 9.4.7, can both hd1.1 and hd1.2 be formatted? If so, what tweaks do i nee dot make to that image2disk command?

 

 

Thanks in advance!
