script to convert bits of config from bigip 10.x to 11.5.x format

The best solution is to backup the configuration, import then restore it on a 11.5 virtual appliance with the command :

load sys ucs yourbackup.ucs no-license no-platform-check 

The restore operation will upgrade your configuration from version 10 to version 11.5. you will then be able to read piece of configuration with tmsh:

list ltm virtual Name of virtual
list ltm pool "name of the pool"
list ltm pool "name of the pool" one-line (to get all the parameters in one line)

On the target appliance, you can import these pieces of configurations with:

load sys config merge from-terminal
    paste the configuration
    CTRL-D
