iRules for 11.5 TMOS running on 11.3 TMOS

I am involved with upgrading my company's iRules to be compatible with version 11.5.1 HF5 TMOS. I made the changes suggested here: https://support.f5.com/kb/en-us/solutions/public/14000/300/sol14381...

In other words, should I be concerned that the changes I put in for 11.5 will not act the same when run under the 11.3 TMOS?

i understand POLICY:: command is introduced in 11.4.0.

BIG-IP LTM v11.4.0

Thanks. I did some more digging around yesterday and found that also. The conclusion is that any iRules that are triggered by the HTTP_CLASS_SELECTED or HTTTP_CLASS_FAILED events will not run (or even load into) 11.5; and that if the iRules are updated for 11.5, they will not work on 11.3 (because the POLICY package doesn't exist in 11.3).
