Hi JB what version of 10.x you have specifically?
However I recently upgraded few pairs from 10.2.1 to 11.3HF4 (F5 said that 10.2.3 would be a good option to choose) and following are the mandatory changes to take care about:
Modifications/Changes required in existing configuration:
"matchclass" needs to be replaced with "class match" (Reference: https://devcentral.f5.com/wiki/irules.class.ashx)
Example:
Old syntax
if { ![matchclass [HTTP::method] equals $::safe_http_methods] }
Required syntax
if { ![class match -- [HTTP::method] equals $::safe_http_methods] }
Also in case you are using some variables like string arrays then you may modify them to a string class for better manageability (a good to have option)
Old syntax
if { ![matchclass [HTTP::method] equals $::safe_http_methods] }
Required syntax with “safe_http_methods” as a class
if { ![class match -- [HTTP::method] equals $safe_http_methods] }
The class/data-group will look something like:
ltm data-group safe_http_methods {
records {
DELETE { }
GET { }
HEAD { }
OPTIONS { }
POST { }
PUT { }
}
type string
}
Follow this while upgrading:

Also the failover configuration is totally different in 11.x so you need to create the failover again, following KBs should help:

Let me know if you need more clarity on specific areas
Thanks
