If the last octet is going to stay the same and you are going to edit ALL virtual servers you can use the method.

tmsh edit ltm virtual all
(this will open a vi editor)

use the search an replace function to replace. It will replace "192.168.11." with "192.168.11." 

:%s/192\.168\.11\./192\.168\.12\./g

esc

:wq

Naturally you should test this, preferably in a dev environment first. Changing IP addresses on virtual servers will terminate existing connections so preferable to do this outside of business hours and on a standby device first.
